Various processes produce dirty gases at high temperature. Accordingly, ceramic filters are used in industrial processes to protect downstream components and environment, and also to save energy. Silicon carbide is commonly applied as a filter material because of its special properties such as high temperature strength and thermal shock resistance. However, based on engineering reports, a major disadvantage of SiC-based filter is its oxidation to SiO2 in high temperature and humid environments. In addition, available methods to fabricate high temperature filter are not capable to control properly the pore size distribution, porosity, and mechanical stability of filer which are the key factors in filtration efficiency.

各种工艺都会在高温下产生肮脏的气体。因此，陶瓷过滤器用于工业过程中，以保护下游组件和环境，并节省能源。碳化硅由于其特殊的性能，如高温强度和抗热震性，通常用作过滤材料。然而，基于工程报告，SiC基过滤器的主要缺点是其在高温和潮湿环境中氧化成SiO2。此外，现有的高温过滤器的制造方法不能适当地控制过滤器的孔径分布、孔隙率和机械稳定性，而这些是过滤效率的关键因素。
