Abstract: A novel tape casting and isostatic pressing combined technique was used to prepare YSZ membranes. 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 the isostatic pressing can raise the green tape density by 8%~11% and the as-sintered tape density by 5%~10%,
and the electrical conductivity of as-sintered tape exhibited a small improvement. The combined forming technique is not complicated and
can be used for a scale fabrication of ceramic tape.

Key words: tape casting, isostatic pressing, YSZ ceramic membrane
