Thermal diffusivity measurements of silicate melts at high temperature have systematically been made by applying the differential three layered laser flash method. Data processing has also been developed in order to separate the contribution due to radiative component from measured values at high temperature by considering the variation of the absorption coefficients when adding TiO2 ZrO2 or iron oxide. The ability of thermal diffusivity measurement system for micro region of composite based on the thermoreflectance method is also demonstrated by using the result of NbTi/Cu composite.
