Method for preparing stabilized zirconia raw material

The invention belongs to the technical field of material chemistry, and particularly relates to a method for preparing a stabilized zirconia raw material. The method for preparing the stabilized zirconia raw material comprises the following steps of: adding a stabilizer which exists in the form of an oxide or salt into a zirconium salt, uniformly mixing the zirconium salt with the stabilizer by adopting a mechanical mixing method, increasing the temperature of the mixture to 900-1100 DEG C at the speed of 150-300 DEG C per hour, preserving heat for 0.5-1 hour for calcining, cooling to the temperature of 400-500 DRGC at the speed of 150-300 DEG C per hour, and cooling naturally to obtain the stabilized zirconia raw material. The stabilized zirconia raw material prepared by adopting the method can react uniformly and thoroughly and has a good stabilization effect, and the performance of a zirconia ceramic product produced from the stabilized zirconia raw material is similar to that of a ceramic product produced from the stabilized zirconia powder which is prepared by adopting the chemical coprecipitation process. The density of the stabilized zirconia raw material is more than 98% of the theoretical density, and the stabilized zirconia raw material can completely replace the stabilized zirconia material prepared by adopting the chemical coprecipitation process to be applied to various fields. The process for preparing the stabilized zirconia raw material is simple, and the cost is reduced greatly.
