Porous ceramics is a new type of ceramics, also known as porous functional ceramics. It is a kind of ceramic that is fired at high temperature after forming, and has a large number of connected or closed holes in the body.
Porous ceramic materials have a small volume density, large specific surface area, low thermal conductivity of the unique porous structure, with high temperature resistance, high strength, good chemical stability, etc., in environmental protection, energy saving, chemical industry, smelting, food, pharmaceutical, biomedicine and other fields have been widely used.
