Abstract

Homogeneously dispersed zirconia suspension was prepared by addition of 500ppm polyvinyl alcohol (PVA). The powder compact by centrifugal casting from this suspension shows more uniform packing, higher packing density, and smaller pore size than that of suspension without PVA. On using this powder compacts, sintered monocllnic zirconia with the relative density of 98% could be obtained at low temperature of 125$0^{\circ}C$.
