摘　　要：本文报道了ＹＳＺ陶瓷膜流延等静压复合成型的新工艺．研究了等静压对素坯膜和烧结膜材密度及显微结构的影响规律及电学性能的变化．指出对流延素坯膜进行等静压，工艺过程不复杂，但可使素坯的成型密度提高８％～１１％，同时烧结膜材的相对密度可提高５％～１０％A novel tape casting and isostatic pressing combined technique was used to prepare YSZmembranes. The effects of isostatic pressing on green and as-sintered tape density and microstructure as well as electrical conductivity were measured and observed. The results showed that theisostatic pressing can raise the green tape density by 8%~11% and the as-sintered tape density by5%~10%, and the electrical conductivity of as-sintered tape exhibited a small improvement. Thecombined forming technique is not complicated and can be used for a scale fabrication of ceramictape.
