Abstract

In this study, sintered bodies of ZrO2 nanopowders were fabricated by combined application of magnetic pulsed compaction (MPC) and subsequent sintering and finally, their density and shrinkage were investigated. The Optimum mixing conditions of PVA, water, and TiO2 nanopowder for compaction was found to be 1.8 mass% PVA, 10.7 mass% water, and 87.5 mass% of ZrO2 powder at the sintered bulks. High pressure and rapid compaction using magnetic pulsed compaction (MPC), enhanced the density with increasing MPC pressure up to 3.5 GPa and significantly reduced the shrinkage rate (about 10–12% in this case) of the sintered bulks compared to the general process (about 18%).
