Research

My research is primarily focused on resource recovery and materials process engineering. Current interests are the development of new production technology for metals, such as titanium (Ti), platinum group metals (PGMs), gallium (Ga), and rare earth metals (REMs):
a) Development of an efficient recovery process for value added inorganic materials (PGMs, REMs)
b) Research on new production process of Ti
c) Production of rare metal powder (Nb, Ta, etc.) for electronic materials
d) Thermodynamics of nitrides, oxides, chlorides, and their complexes at elevated temperatures
