The Additive Porous Ceramic Technology involves adding pore-forming agents to ceramic raw materials, utilizing these agents to occupy space within the green body, followed by sintering, where the pore-forming agents are removed, resulting in the formation of pores to create porous ceramics. The process of producing porous ceramics with pore-forming agents is similar to the conventional ceramic process. Pore-forming agents are categorized into inorganic and organic types, with inorganic pore-forming agents including high-temperature decomposable salts like ammonium carbonate, ammonium bicarbonate, and ammonium chloride, as well as coal powder and carbon powder.
