Preparation technology of fully stabilized zirconia ceramic material

1. Ingredients: Mix the matrix, α-alumina whiskers and adhesives mechanically in proportion. The mixing equipment can be a stirring ball mill, a V-type mixer, a planetary ball mill, etc.

2. Forming: In the forming machine, the mixed ingredients are made into a green body. The molding method can be selected from compression molding, isostatic pressing, hot die casting, injection molding, slurry molding, and the like.

3. Sintering: put the green body in a sintering furnace at 1300-1800℃ for 1-3 hours. Can be sintered under vacuum, partial pressure, no pressure or pressurized environment. The sintering atmosphere may be air, nitrogen, or the like. Usually, pressureless sintering in air atmosphere can be used, and the sintering temperature is between 1550-1670 °C.
