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

摘要

Disclosed are a porous ceramic having a double layer pore structure having a laminate structure divided into a compact layer with limited pores, and a porous layer integrally laminated on the compact layer by being manufactured by mixing a ceramic powder with high specific gravity and a hollow polymer pore forming agent with low specific gravity, and a manufacturing method thereof. The porous ceramic having a double layer pore structure according to the present invention is formed by mixing a ceramic powder having first density and a hollow polymer pore forming agent having second density, and comprises a compact layer with limited pores; and a porous layer having a laminate structure integrally laminated on the compact layer, and having porosity of 50-80% by spherical pores. The part composed of the compact with limited pores has a composite function of enduring mechanical load and weight which porous ceramic cannot endure.
