Research Activities
The aim of our research is to refine materials for high quality and development of materials processing. Our research fields are the fundamental study of the physical chemistry of high temperature reactions between solids, liquids and gases, and the development of processing of advanced materials. Our investigations are focused on melts of metals and oxides. The development of new refining processes in non-equilibrium states, and material recycling for solving environmental and resource issues are conducted.
Research activities for materials processing are as follows:
(1) Kinetics of chemical reactions between liquid metals, molten oxides and gases by the isotope exchange technique.
(2) Development for effective utilization of biomass energy in materials processing.
(3) Design of new fluxes for refining of molten metals for high quality.
(4) Development of raw materials and fluxes for advanced iron and steel making.
(5) Development of a process for producing fine powders of metals and compounds by chemical vapor deposition.
Research activities for environmentally conscious materials and recycling are as follows:
(1) Development of techniques for selective recovery and refining of recycled metals.
(2) Analysis of formation of oxyhalides compounds in the recycling process and development of new recycling processes.
(3) Investigation of materials flow in order to reduce the environmental load.
In addition, molecular dynamics simulation is a powerful method for the estimating thermodynamic and kinetic properties of materials that are difficult to measure by experiment. A method for calculating thermodynamic properties and phase diagrams of ionic melts at high temperatures is being investigated.
By combining experiments and simulations, we are trying to develop new materials processing that is suitable for a sustainable society.
