Zirconia powder, product thereof and preparation method thereof
The invention discloses zirconia powder, a product thereof and a preparation method thereof. The zirconia powder is characterized in that the principle components of the zirconia powder are ZrO2, HfO2 and MxOy, wherein the MxOy is metallic oxide, the mole percentage of the content of the MxOy of the main components is smaller than or equal to 15%, M is one or more of Y, Ca, Mg, Ce, Pr, V, Mo and Ti, the mass percentage of the main components is more than 90% of the zirconia powder, and the mass percentages of the other metallic oxides except the main components of the zirconia powder are smaller than or equal to 0.01%. The method comprises a step of solid-liquid separation under specific pH values, wherein the step is carried out twice. Compression bodies made of the zirconia powder are high in purity, good in mechanical performance, used for preparing ceramic materials, low in radioactivity, and capable of serving as biological ceramic materials such as false teeth and artificial bones.
