以二氧化硅粉为无机粉料，玻璃粉为粘合剂，通过改变组分配比，实现了对陶瓷支撑体热膨胀系数的调节，从而使支撑体与表层硅基裂解膜热膨胀系数保持一致，以防止在高温条件下膜的龟裂．同时，通过调节无机粉料及成孔剂等组分粒径的大小及其分布，控制陶瓷支撑体的孔结构．制备出孔结构、强度，以及热膨胀系数等多方面，满足要求的多孔陶瓷支撑体．
By using silica powder as inorganic powder and glass powder as binder, the thermal expansion coefficient of the ceramic support can be adjusted by changing the composition ratio, so that the thermal expansion coefficient of the support and the surface silicon-based cracking film are the same Prevent cracking of the film at high temperature. Meanwhile, the pore structure of the ceramic support body is controlled by adjusting the size and distribution of the components such as inorganic powder and pore forming agent. Prepared porous structure, strength, and thermal expansion coefficient and other aspects to meet the requirements of porous ceramic support body.
