Method for preparing zirconium-yttrium and zirconium-aluminum composite powder with yttria-stabilized zirconia solid waste
The invention relates to a method for preparing zirconium-yttrium and zirconium-aluminum composite powder with yttria-stabilized zirconia solid waste, and belongs to the technical field of ceramic waste recycling. The method for preparing the zirconium-yttrium and zirconium-aluminum composite powder with the yttria-stabilized zirconia solid waste comprises the steps that zirconium sulfate and yttrium lixivium prepared through a sulfuric acid acidification method is extracted through an extraction agent to obtain zirconium-yttrium purification liquid; a precursor of the zirconium-yttrium and zirconium-aluminum composite powder is prepared through a coprecipitation method, and the precursor is sintered to obtain the zirconium-yttrium and zirconium-aluminum composite powder. The method for preparing the zirconium-yttrium and zirconium-aluminum composite powder with the yttria-stabilized zirconia solid waste is low in cost, simple in process step, and high in recovery rate on zirconium and yttrium metal.
