Fused monoclinic zirconia powder be used in ceramic pigment(high temperature Pr-yellow and coral pink), ceramic sand cushion, sizing nozzle, refractory material for sliding plate, high temperature kiln furniture, special glass, structural ceramics, zirconia welding rod, auto brake pad additives etc, especially in high-end refractories, it can significantly raise the sintered density, increase thermal-shock resistance, decrease the sintering temperature. Our monoclinic zirconia powder have the characteristics of high purity, high activity, high specific surface area, low sintering temperature.
