| Research Abstract |
Mullite and silicon carbide that have an anisotropic crystal structure and show high corrosion resistance, thermal and mechanical properties were selected as candidate materials, and fundamental studies on the development of high performance porous ceramics for exhaust gas filter based on in-situ crystal growth, grain orientation and morphology control on the wall of pores and the surface of the sintered body in porous ceramics during sintering or heat-treatment were performed. As a result, high performance porous mullite and silicon carbide with a unique morphology and relatively homogeneous pore-size distribution were successfully achieved.
