Fabrication of Nano Y-TZP by Rapid Hot-Pressing and SPS

Abstract

Abstract: Ultrafine 3Y-TZP materials were fabricated by the rapid hot-pressing and SPS(Spark Plasma Sintering). It was found that although
the relative densities of the Y-TZP sintered by the two kinds of rapid rate sintering methods were higher than that of sintered by ordinary
hot-pressing at the similar sintering temperature, the grain sizes were larger than that obtained by pressureless sintering; On the other hand,
the structure of the samples sintered by SPS was much homogeneous than that sintered by rapid hot-pressing. The reasons of those phenomena were
also discussed. By choosing appropriate condition, ultrafine 3Y-TZP materials with a relative density of 99% could be gotten by both the two
kinds of rapid rate sintering.

Key words: ultrafine 3Y-TZP, SPS, rapid hot-pressing
