Study on Isostatic Pressing YSZ Membrane Fabricated by Tape Casting

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.
