Nano brown zirconium oxide powder and preparation method thereof
The invention relates to nano brown zirconium oxide powder and a preparation method thereof. The nano brown zirconium oxide powder comprises 0.5-1.5 parts of iron ions, 0.1-1 part of copper ions, 87.5-98.4 parts of zirconium ions and 1-10 parts of yttrium ions. The granularity of the nano zirconium oxide powder meets the conditions that D50 is less than or equal to 0.06 microns and D100 is less than or equal to 0.15 microns. In order to obtain the powder, the preparation method comprises the following steps: (1) dissolving a soluble iron compound, a copper compound and zirconium oxychloride in water according to a certain proportion, and then adding yttrium oxide at the dissolving temperature of 40-60 DEG C to obtain a brown zirconium compound mixed solution; (2) carrying out hydrolysis reaction on the brown zirconium compound mixed solution in the step (1) to obtain iron-copper-zirconium oxide mixed slurry; (3) rinsing and drying the mixed slurry in the step (2), and then carrying out thermal decomposition reaction; and (4) carrying out ball milling and spray granulation treatment on the thermal decomposition product in the step (3) to obtain the brown nano zirconium oxide powder for the ceramic mobile phone shell.
