    Abstract This study aimed to accurately measure the density (ρ), normal spectral emissivity (ε), heat capacity at constant pressure (C p ), and thermal conductivity (κ) of the Ti–6 mass % Al–4 mass % V (Ti64) melt by electromagnetic levitation with a static magnetic field and laser modulation calorimetry. A static magnetic field was applied to the levitated Ti64 melt to suppress the surface oscillation and translational motion of the droplets, and to suppress the convection flow inside the droplet for each property measurement, as needed. The measurement uncertainty was analyzed for all of the thermophysical property data. The excess volume and excess heat capacity of the Ti64 melt obtained in this study were compared with those evaluated using the ideal solution model. The contribution of the thermal vibrations of the atoms in κ for the Ti64 melt was evaluated from the difference between the measured thermal conductivity (κ) value and the κ values calculated using the Wiedemann–Franz law.

    Abstract The temperature dependence of density, normal spectral emissivity, heat capacity at constant pressure, and thermal conductivity of the V melt were measured with high accuracy using electromagnetic levitation in a static magnetic field. Surface vibration, translational motion, and convection of the electromagnetically levitated droplet sample were suppressed by the magnetic field. In the measurement of thermal conductivity, convection in the V-melt was sufficiently suppressed by the application of a field of 7 T or higher. In this study, the measured emissivity and thermal conductivity are compared with those evaluated using the free-electron models (Drude model and Wiedemann–Franz rule). Correlations between the density of states and thermal diffusivity at the Fermi energy of transition metals in the liquid state are investigated and the applicability of Mott's s–d scattering model is discussed.

    We propose a new AlN crystal growth method using Fe-based fluxes. AlN single crystals with a thickness of 67–212 µm were epitaxially grown on an AlN bulk substrate by a solution growth method using type 430 ferritic stainless steel flux. The full width at half maximum values of the x-ray rocking curves of (0002) and (10–12) of the synthesized AlN were 137 and 83 arcsec, respectively. The impurity concentrations of carbon were significantly decreased from 3 × 1019 atoms/cm3 in seed crystal to 6 × 1017 atoms/cm3 in synthesized crystal. The features of the method developed in this study are described as follows: (1) steel-based alloys are used as a flux, which are readily available and low-cost; (2) the growth temperature is 1700 °C, which is much lower than that of the sublimation method; (3) no high-pressure vessel is required because growth can be performed under 1 atmospheric pressure conditions; and (4) waste gas detoxification equipment is not required because only N2 gas is used and no toxic or flammable gases are used. Because of the above features (1) through (4), this is an effective crystal growth process from the perspective of ensuring the economics and safety of the facility.

    Abstract This study is part of a series of studies aimed at measuring the thermophysical properties of molten phase change material-type metallic thermal energy storage materials near 873 K (600°C). The target material is Al–Si based alloys. First, as a feasibility study, density measurements of the molten state of three Al–Si binary alloys (Al–12.2Si, Al–50Si and Al–90Si in atomic%) were performed. A highly accurate non-contact density measurement method based on the static magnetic field superposition electromagnetic levitation (EML) method was employed as the density measurement method. The validity of this experimental method was confirmed, and density of molten Al–Si base alloys (ADC12 and Al–5.9mass%Si–1.6mass%Fe) were measured as a function of temperature with an expanded uncertainty of 1.2%. In addition, the surface tension of the alloys was measured by the droplet oscillation method using the EML technique. The surface tension was successfully obtained as a function of temperature with expanded uncertainty of 2.3%.

    The applicability of the dual-wavelength reflectance-ratio (DWR) method to emissivity-free radiation thermometry of electromagnetically levitated high-temperature liquid metals was investigated. To establish the measurement technique, the DWR method was applied to liquid Ni levitated in a static magnetic field, which suppresses the surface oscillation and the translational motion. In a previous study, temperature of the levitated liquid metals measured by DWR showed deviations of about 95 K to 175 K from the temperature measured by a calibrated pyrometer. Since this discrepancy could be attributed to the imperfect contribution of the auxiliary light, the effect of the optical setup of the auxiliary light on the temperature measurement was investigated in this study. By using a reflecting collimator for the auxiliary optical system and adopting the radiance ratio determined considering the geometrical arrangement of the measurement system, the difference between temperature of liquid Ni kept near its melting temperature (𝑇𝑚 = 1728 K) measured using DWR and the temperature measured by a pyrometer calibrated using the melting point of Ni was 12 K on average and the standard deviation in the temperature measurement was 25 K (𝑛 = 5).

    The normal spectral emissivity at 807 and 940 nm and heat capacity at constant pressure of Pd–Fe melts were measured under electromagnetic levitation with a static magnetic field. The samples were made of Fe of mass purity 99.9985%. The present emissivity of Fe melts was relatively low compared with previously reported data using Fe with purity lower than 99.95% mass purity. The spectral emission of the Fe melts was analyzed using their normal spectral emissivity obtained from the Drude model. The excess heat capacity of Pd–Fe melts was evaluated from the measured heat capacity of Pd–Fe melts. Applying the Lupis–Elliot rule, we concluded from the obtained excess heat capacity that the enthalpy of mixing and excess entropy of the Pd–Fe melts should be negative. The composition dependence of the enthalpy of mixing, excess entropy, and excess Gibbs energy of Pd–Fe melts were evaluated using data obtained in this study and the literature.

    Abstract This article describes a preliminary study verifying the applicability of the dual-wavelength reflectance-ratio (DWR) method to emissivity-free radiation thermometry for electromagnetically levitated high-temperature liquid metals. To establish the measurement technique, the DWR method was applied to inductively heated solid spherical Cu and Ni samples. Regardless of the differences in the sample emissivity values, the temperature determined using the DWR method agreed within 20 K with the temperature determined using a thermocouple. It was found that the temperatures of metallic samples having different emissivity values can be determined with a standard uncertainty of 8 K in terms of the absolute temperature when applying the DWR method, even if the sample has curvature and is exposed to high temperatures of up to 1250 K.

    Temperature dependent isobaric molar heat capacity cP was measured in a containerless way for liquid Ti and two AlTi binary liquid alloys. The technique of electromagnetic levitation was used in combination with laser modulation calorimetry. In all cases, linear temperature dependencies were found: At the corresponding liquidus temperatures, cP equals 49.75(±2.0) J∙K-1mol-1, 57.43(±2.9) J∙K-1mol-1, and 42.60(±2.2) J∙K-1mol-1, for Ti, Al20Ti80 and Al50Ti50, respectively. The respective temperature coefficients amount to -1.67∙10-2J∙K-2mol-1, -2.73∙10-2J∙K-2mol-1, and +7.83∙10-2J∙K-2mol-1. For liquid Ti, there is a good agreement with existing literature data. The results are discussed in relation to the Neumann-Kopp rule.

    Abstract One of the key issues in a core disruptive accident (CDA) evaluation in sodium-cooled fast reactors is eutectic reactions between boron carbide (B4C) and stainless steel (SS) as well as its relocation. Such behaviors have never been simulated in CDA numerical analyses in the past, therefore it is necessary to develop a physical model and incorporate the model into the CDA analysis code. This study focuses on B4C-SS eutectic melting experiments, thermophysical property measurement of the eutectic melt, and physical model development for the eutectic melting reaction. The eutectic experiments involve the visualization experiments, eutectic reaction rate experiments and material analyses. The thermophysical properties are measured in a range from solid to liquid state. The physical model is developed for a CDA computer code based on the measured data of the eutectic reaction rate and the physical properties. This paper describes the project overview and progress of experimental and analytical studies conducted until 2019. Specific results in this paper are the validation of physical model describing B4C-SS eutectic reaction in the CDA analysis code, SIMMER-III, through the numerical analysis of the B4C-SS eutectic melting experiments in which a B4C block was placed in a SS pool.

    We have developed the system PROSPECT for measuring thermophysical properties at high temperature. Precise thermophysical measurements provide accurate excess functions, which represent non-ideality of solutions. We use excess functions to discuss solution models on the basis of electronic structure and thermodynamics. Pd-Fe systems show positive excess volume VE with negative excess Gibbs energy GE. The phase diagrams of these systems have common features with those of other Pd-X and Pt-X systems (where X is Fe, Ni, Co, or Cu), which means they all have order-disorder transitions. The correlation between VE and GE is discussed in terms of the electronic structure of the alloys, and an energy diagram is proposed to understand this correlation. The excess heat capacity CpE of Fe-Ni melts is positive over a whole composition range and a wide temperature range. We estimate the temperature dependences of the excess enthalpy HE and excess entropy SE of Fe-Ni melts from CpE. The Lupis-Elliott rule is satisfied for HE and SE with positive CpE.

    Surface tensions of electromagnetically levitated liquid Ti-samples were measured under the influence of oxygen. For this purpose, Ti-O samples were prepared by adding different amounts of TiO2 powder to pure Ti. The surface tension was found to strongly depend on the bulk oxygen mole fraction determined by chemical analysis.The results could be described by a simple model presented in the present work. In this model the Butler equation is applied and the formation of TiO2 – associates are taken into account. Non-ideal interactions ΔH≠0 between titanium and the associates also need to be taken into account. Good agreement with the experimental data is evident and also with a different model developed earlier by us.

    A method of accurately measuring the densities of high-temperature liquids levitated by electromagnetic levitation (EML) technique within the static magnetic fields is proposed. The method is based on the electromagnetic effect on the moving electrical conductivity materials. The liquid metal sample levitated by EML technique is oscillating by the electromagnetic force, and also is moving in the coils. For the liquid samples, if we apply a static magnetic field, the Lorentz force by the interaction between the electrical conductive sample and the static magnetic fields reduces the surface oscillation and translational motion of samples. For the effect, we can precisely obtain the correct volume of levitated liquid samples like a solid body. For applying the technique, we can measure the density of high-temperature liquid silicon in the range 1100 to 2000K. Using the technique we succeeded to reduce an order of magnitude compared with previously reported data. From the precise measurement of liquid silicon density, we found that the density has the maximum value in undercooled regions expected from the first principle molecular dynamics (FPMD) simulations. We also performed the structural analysis of liquid silicon by x-ray diffraction combined with the EML technique. Based on these results, we discuss about the temperature dependence of liquid silicon density from the view point of the structure of liquid silicon based on the tetrahedral coordination in the short range order. From these discussions, we show the importance of density measurement of high-temperature liquids for crystal growth simulations and understanding of the liquid structure and properties.
