Preparation method of nano zirconia coated alumina powder
The invention discloses a preparation method of nano zirconia coated alumina powder. The preparation method comprises the steps of by taking alumina as a main material, preparing zirconium oxychloride and yttrium chloride into a mixed solution; by taking urea or hexamethylenetetramine as a homogenous precipitation agent, carrying out temperature regulation to form a zirconium hydroxide coating layer on the surface of the alumina; and carrying out spray drying on the obtained object so as to obtain precursor powder, and calcining the precursor powder to obtain the nano zirconia coated alumina powder.
