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.

选择具有各向异性晶体结构并显示出高耐腐蚀性、热性能和机械性能的莫来石和碳化硅作为候选材料，并对基于原位晶体生长的用于废气过滤器的高性能多孔陶瓷的开发进行基础研究，在烧结或加热过程中多孔陶瓷中孔壁和烧结体表面上的晶粒取向和形貌控制，进行治疗。结果，成功地获得了具有独特形貌和相对均匀的孔径分布的高性能多孔莫来石和碳化硅。
