采用喷涂法在碳化硅(SiC)支撑体上覆膜,根据碳化硅材料的氧化特性,设计了有氧烧结和氩气烧结随温度转换的组合烧结制度,并通过优化保温时间降低碳化硅陶瓷膜烧结成本。研究结果表明,新的烧结制度能有效地控制有氧烧结阶段产生的二氧化硅(SiO
2
)量,并促进其与烧结助剂氧化锆(ZrO
2
)等在气氛烧结阶段的反应,反应生成的锆英石相和添加莫来石相共同形成SiC颗粒连接颈部。制备的碳化硅陶瓷膜平均孔径为3.03 μm,气体通量为175 m

Spray-coating was used to prepared silicon carbide (SiC) membranes on the surface of SiC supports
then the coated samples were sintered by switching sintering atmospheres (aerobic to argon) over different temperature ranges according to the oxidation characteristics of SiC
and the sintering cost of SiC ceramic membranes was reduced by optimizing the soaking time. The results revealed that the new sintering procedures can effectively control the oxidation of SiC in the aerobic sintering stage
and promoted its oxidation product silica (SiO

) reaction with the sintering aids such as zirconia (ZrO
2
) in the argon sintering stage. The average pore size of the prepared SiC ceramic membrane was 3.03 μm and the gas permeation was 175 m
