Title:
METHOD FOR PRODUCING POROUS CERAMIC MATERIAL, POROUS CERAMIC MATERIAL, SETTER, AND FIRING JIG
Document Type and Number:
WIPO Patent Application WO/2015/087664
Kind Code:
A1
Abstract:
A method for producing a porous ceramic material according to an embodiment comprises the steps of: gelatinizing a suspension; freezing the gelatinized suspension to produce a frozen material; removing ice that is grown in the frozen material to form pores in the frozen material; and firing the ice-removed frozen material. The suspension comprises ceramic particles, a water-soluble polymer and water. The viscosity (η (mPa·s)) of the suspension that is not gelatinized yet at 20°C and the average particle diameter (d (μm)) of the ceramic particles have a relationship represented by the formula: η ≥ 950 × d-0.77.
