Preparation method for nanometer zirconia powder
A preparation method for nanometer zirconia powder is characterized by including the following steps of introducing argon till the pressure is 40 mbar under the pressure of 0.2 mbar through an ultralow pressure-plasma spraying method, reducing the pressure to 0.5 mbar, conducting plasma spraying on ZrO2 powder with the particle size of 15-45 micrometers under the spraying power of 90-150 kW, the argon flow of 35-50 SLPM, the helium flow of 50-70 SLPM and the powder feeding speed of 20-35 g/min for 60-90 min, and obtaining the high-oxygen-vacancy nanometer zirconia powder. The preparation method for the nanometer zirconia powder is high in efficiency, capable of achieving industrialized production and low in cost, the prepared nanometer zirconia powder has high oxygen vacancy, and the powder is black.
