ABSTRACT:
A zirconia powder has an average particle diameter in a range from larger than 0.5 .mu.m to 0.8 .mu.m, and particles of 90 volume percent of the zirconia powder having a diameter of 1.5 .mu.m or smaller. Using this zirconia powder, a zirconia ceramics having uniform quality can be produced. The zirconia powder of the present invention can be efficiently produced by wet-milling a raw material powder using balls under a condition satisfying the following mathematical relation (I):
