摘    要:多孔碳化硅(SiC)陶瓷具有力学性能优异、耐腐蚀、耐高温和热导率高等优点,在冶金、化工、环保和能源等领域拥有广阔的应用前景。综述多孔SiC陶瓷的孔隙特性、力学性能和导热性能;将常用的多孔SiC陶瓷制备方法分为4类并加以阐述,即颗粒堆积烧结法、模板法、添加造孔剂法和直接发泡成形法;介绍多孔SiC陶瓷的应用;展望多孔SiC陶瓷的发展方向。

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.
