High-temperature processes and measurements of materials

Fukuyama laboratory studies novel material processing based on chemical thermodynamics with high-temperature thermophysical property measurements. Currently, we are developing new crystal growth processes to bring a breakthrough in nitride-semiconductor devices, which are promising materials for next-generation optical devices applied in environmental, medical, bio and information technologies fields. Database of thermophysical properties of materials is needed for modeling heat and mass transports in materials processes. The world' first thermophysical property measurement system has been developed in our laboratory, which enables accurate measurements of heat capacity, thermal conductivity, emissivity, density and surface tension of high-temperature melts, utilizing electromagnetic levitation in a dc magnetic field.
