Sintered bulks of commercial ZrO2 nanopowders were produced by combined application of magnetic pulsed compaction (MPC) and subsequent two-step sintering, and finally, their density, hardness, shrinkage and formability were analyzed. The formability tests were conducted by a CAD/CAM system. Nearly fully dense (similar to 98%) commercial ZrO2 bulks were successfully obtained. With increasing MPC pressure, there was a decrease in the grain size of zirconia block. The ratio of PVA did not have a remarkable effect on the grain size. The optimum compaction pressure during MPC was 1 GPa and mixing conditions included using 1.0 wt. % PVA. The optimum processing condition included MPC process, followed by two-step sintering (first at 1000 and then at 1450 degrees C). The bulk under these conditions was found to have good formability, similar to 97% density, reasonable hardness (1150 Hv) and similar to 19% shrinkage. (C) 2013 Elsevier B.V. All rights reserved.
