PORE-IMPARTING MATERIAL, POROUS MATERIAL FORMING RAW MATERIAL CONSISTING OF PORE-IMPARTING MATERIAL, AND POROUS MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a new pore-imparting material containing an extinction granulated powder as a main component, a porous material forming raw material consisting of the pore-imparting material, and a porous member.;SOLUTION: The pore-imparting material is characterized by containing, as a main component, the extinction granulated powder obtained by granulating an extinction material which disappears mainly by heating. The porous material forming raw material contains the pore-imparting material as a main component and a forming raw material powder. The porous member having granular pores not connecting neighboring other pores and maintaining the property of the forming raw material powder is obtained by forming the porous material forming raw material and firing the formed body.;COPYRIGHT: (C)2004,JPO
