Abstract

PURPOSE:To obtain a porous ceramics material having excellent thermal shock resistance, by coating ceramic particles having a specific thermal expansion coefficient with a glassy bonding particles having a specific thermal expansion coefficient and specified composition, and sintering those particles at a specific temp. CONSTITUTION:A ceramic material obtained by coating ceramic particles having 3X10<-6>-9X10<-6>/ deg.C thermal expansion coefficient with glassy bonding particles having 1.5X10<-6>-7X10<-6>/ deg.C thermal expansion coefficient which is 0.5X10<-6>-3X10<-6>/ deg.C lower than that of the above-mentioned ceramic particles, 60-100wt.% neutral oxide, 0-35wt.% acidic oxides and the remainder of basic oxides and impurities and sintering the resultant coated particles at a higher temperature than the melting point of the glassy boning material.
