POROUS CERAMIC HAVING DOUBLE LAYER PORE STRUCTURE AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed in the present invention are porous ceramic having a double layer pore structure, and a manufacturing method thereof. The porous ceramic is manufactured by mixing ceramic powder having a high specific gravity with a polymer hollow pore forming agent having a low specific gravity, and has a layer structure divided into a compact layer having suppressed pores and a porous layer formed by being integrally laminated on the compact layer. The porous ceramic having a double layer pore structure is porous ceramic manufactured by mixing ceramic powder having a first density with a polymer hollow pore forming agent having a second density lower than the first density. The porous ceramic having a double layer pore structure comprises: a compact layer having suppressed pores; and a porous layer having a layer structure formed by being integrally laminated on the compact layer, and having a porosity of 50 to 80% induced by spherical pores.
