| titleOfInvention | A kind of red zirconia ceramic and preparation method thereof |
| abstract | The invention discloses a red zirconia ceramic and a preparation method thereof. In the technical field of engineering ceramic materials, the zirconia powder of yttrium oxide stabilizer, an aqueous solution containing chromium element salt and additives are directly mixed uniformly; The mass ratio of the aqueous solution of the salt to the mass ratio of the zirconia powder containing the yttrium oxide stabilizer is 0.3:1 to 3:1, and the addition amount of the additive is 5 to 20% of the mass of the aqueous solution containing the chromium element salt; Drying and molding to obtain a ceramic body; sintering the ceramic body at a temperature of 1400-1600 DEG C in an air atmosphere for a holding time of 0.5-4h to obtain red zirconia ceramics. The preparation method of the invention is simple in process, the sintering atmosphere of the ceramic body adopts an oxidizing atmosphere, no vacuum or reducing atmosphere is required, and the cost is low; the content of chromium element in the ceramic is low, and the mechanical properties of the ceramic are not affected. |
