Raw material powder for composite-grain zirconia ceramics with high wear resistance and preparation process of raw material powder
The invention discloses raw material powder for composite-grain zirconia ceramics with high wear resistance and a preparation process of the raw material powder. The raw material powder comprises a main material and a yttrium-stable zirconia clinker, wherein the weight ratio of the yttrium-stable zirconia clinker to the main material is 1: (5-20); the main material is a mixture of zirconium oxychloride and yttrium nitrate; and the molar ratio of zirconium oxychloride to yttrium nitrate is 97:3. The raw material powder disclosed by the invention is high in wear resistance and hardness and corrosion-resistant. A ceramic part made of the raw material powder disclosed by the invention is high in wear resistance and beneficial to continuous and durable application; and the raw material powder is particularly suitable for ceramic knives and can be widely applied to other ceramic equipment or tools with high wear-resistant requirements.
