Description

technical field [0001] The invention relates to a ceramic, in particular to a porous ceramic with good low temperature resistance. Background technique [0002] Ceramics are utensils made from two different types of clay, pottery clay and china clay, through batching, molding, drying, roasting and other processes. Porcelain industry is a traditional industry in my country, and ceramic products are the pillar industry and export competitive product of my country's light industry. Ceramic products include not only daily-use ceramics, but also many types of industrial ceramics. Porous ceramics are one of the industrial ceramics. [0003] The porous ceramic material is a kind of porous ceramic material with open pore size and high open porosity, which is made of corundum sand, silicon carbide, cordierite and other high-quality raw materials as the main material, and is prepared by molding and special high-temperature sintering process. High temperature, high pressure, acid, al...
