摘　　要：用氧化铝或堇青石超细粉为骨料，混合玻璃粉，碳粉润滑剂压成坯料，在１２５０℃时烧成得到表面光滑强度较好的多孔基体．透水率为１０００～３０００ｍＬ／ｃｍ２·ｈ，孔隙率为３０％～４０％．电镜观察表明，表面和断面孔隙为（０．２～６）μｍ，孔隙大小及分布均匀，是一种能做无机复合玻璃膜的较好的多孔基体．Mixing aluminum oxide or ultrafine powder of cordierite, the raw material, with glass powder carbon powder and lubricant, a porous substrate would be sintered at a temperature of 1 250℃. The surface of the sintered substrate is smooth. Its strength is high; its perviousness is 1 000～3 000 mL/m2; Its porosity is 30%～40%；its electron micrographs show that the pore sizes on the surface and on the section of the porous substrate are about(0.2～6)μm. The size of the pores and their distribution are even. Therefore, the sintered substrate is a good porous substrate for the preparation of inorganic composite glass membranes.
