Fabrication of Nano 3Y-TZP by Spark Plasma Sintering

Abstract

Abstract: The SPS(Spark Plasma Sintering) process was used to prepare ultrafine 3Y-TZP materials. It was found that dense samples(>2g) without
crack can be fabricated by SPS process. The density of the samples increases with the rising of sintering temperature and soaking time.
The grain size of the sample also increases with the rising of sintering temperature but the increasing speed will be slow compared with some other
sintering methods. The mechanism of these phenomena was investigated. By choosing appropriate conditions, ultrafine 3Y-TZP materials with grain
size of about 100--130nm and relative density of 98.2% can be made.

Key words: nano 3Y-TZP, SPS
