Method for preparing porous SiOC-based ceramic membrane support by combining laser 3D printing with impregnation cracking process
The invention relates to a method for preparing a porous SiOC-based ceramic membrane support by combining laser 3D printing with an impregnation cracking process, which comprises the following steps: (1) mixing polysiloxane PSO powder, SiC powder and phenolic resin to obtain mixed powder; (2) carrying out printing molding on the obtained mixed powder by using a laser 3D printer to obtain a green body; and (3) placing the obtained green body in liquid PSO, vacuumizing and dipping, placing in an inert atmosphere, and sintering at 1200-1400 DEG C to obtain the porous SiOC-based ceramic membrane support.
本发明涉及一种激光3D打印结合浸渍裂解工艺制备多孔SiOC基陶瓷膜支撑体的方法，包括：(1)将聚硅氧烷PSO粉体、SiC粉体和酚醛树脂混合，得到混合粉体；(2)所得的混合粉体使用激光3D打印机打印成型，得到坯体；(3)将所得坯体置于液态PSO中抽真空浸渍后置于惰性气氛中，在1200～1400℃下烧结，得到所述多孔SiOC基陶瓷膜支撑体。
