Embodiment l
[0027] 1) Use the traditional sintering method to prepare zinc oxide-based ceramic targets: ingredients are prepared according to the following mole percentage components, ZnO96.3%, Bi 2 o 3 0.9%, Sb 2 o 3 1.0%, Co 2 o 3 0.8%, Cr 2 o 3 0.5%, MnO 2 0.5%; use agate balls, stainless steel tanks, and absolute ethanol as the ball milling medium. The mass ratio of agate balls: ingredient powder: absolute ethanol is 2.5:1:1, wet milling in a planetary high-energy ball mill for 5 hours, and the speed is 300rpm; The ball-milled slurry was kept at 70°C for 24 hours to form a dry powder; after adding a 2% PVA aqueous solution to the dry powder, it was pressed with a pressure of 70 MPa to make the powder into a billet; the billet was put into a silicon-molybdenum rod high-temperature electric furnace, First raise from room temperature to 500°C at a rate of 5°C / min, keep warm for 120 minutes in an air atmosphere, then raise to a sintering temperature of 950°C at a rate of 5°C / min, k...
