Abstract

PURPOSE: To produce a ceramic porous body having high porosity and fine pore size and being homogeneous and free from deformation and crack in good productivity, by pressurizing, molding and burning an ultrafine ceramic powder using a specific lubricating organic liquid substance as a molding medium.
CONSTITUTION: A lubricating organic liquid substance such as aliphatic, alicyclic or aromatic hydrocarbon, alcohols, esters or silicone having 2W100 centistokes poise at 37°C and 70W700 average mol.wt. is added to 0.005W2.5μm ultrafine power of ceramics consisting of Al2O3, SiO2, ZrO2, TiO2, SiC, Si3N4, BN and the others as a molding medium at a ratio of 65W330wt.% and the blend is kneaded and molded under pressure and burned at 500W1,400°C. The molding medium is gasified and loosen at high temperature and ultrafine ceramic porous body having 60W90% average porosity can be simply produced in good productivity.
