Abstract:Porous silicon carbide (SiC) ceramic has broad application prospects in metallurgy, chemical industry, environmental protection, and energy due to its advantages, including excellent mechanical properties, high thermal conductivity, corrosion resistance, and high temperature resistance. The porosity characteristic, mechanical properties and heat-conducting property of porous ceramic were reviewed. In addition, the fabrication methods of porous SiC ceramic were elaborated to four kinds: partial sintering, replica, sacrificial template, and direct foaming. The applications of porous SiC ceramic were introduced, and its research directions were predicted.
Key words: SiC; porous ceramics; preparation technology; application
