Abstract

Abstract: A new forming method called RIP was applied to fabricate Y-TZP nano ceramics. With RIP, a high pressure of about 1GPa was attained; a green compact
with a weight of about 16g and a relative density of about 56% wasobtained. Y-TZP nano-ceramics having a grain size of about 70nm were
obtained when sintered at 1100℃ for 2h. The results show that the sintering ability of the green compact is so good that it can be sintered to 97% at a low
temperature of 1100℃. The relative high density of the green compact and the small pore size are the main reasons for the excellent
sintering ability.

Key words: Y-TZP, nanometer, RIP
