| 简介 |
A sintered ceramic compact, characterized in that it comprises ceramic coarse particles and a polycrystalline binding layer composed of ceramic fine particles and/or aggregates thereof which are present among the ceramic coarse particles in such a manner as to link them and have an average particle diameter less than that of said coarse particles; and a ceramic filter manufactured by using the sintered ceramic compact. The sintered ceramic compact or the ceramic filter can suppress the occurrence of a large crack due to the break of particles of silicon carbide in the case wherein a thermal stress is applied to the sintering compact in a re-treatment or the like, can suppress the deterioration of a catalyst carried on it in the case that it is re-treated repeatedly, and thus can be used stably for a long period of time. |
