Abstract
Provided are a zirconium oxide composite ceramic and a preparation method therefor. The zirconium oxide composite ceramic comprises by mass percentage: 65% to 80% of a zirconium oxide matrix, 10% to 30% of a conductive material, and 2% to 11% of a nano-reinforcing material. The conductive material is selected from at least one of a non-ferrous metal oxide, a white metal oxide, a compound having a perovskite structure and a compound having a spinel structure. The zirconium oxide composite ceramic has excellent antistatic properties and high mechanical properties.
