| titleOfInvention | Preparation method of zirconia composite biological ceramic material |
| abstract | The invention provides a preparation method of a zirconia composite biological ceramic material, which comprises the following steps of mixing zirconia powder, yttria powder, β -alumina powder, neodymium oxide powder and cerium oxide powder according to the weight ratio of 90-92: 6.0-9.0: 0.15-0.35: 0.45-0.75: 0.55-0.85 to obtain a mixed material, adding carbon with the weight of 2.0-5.0% of the mixed material into the mixed material, putting the mixed material into an electric arc furnace for high-temperature smelting, continuing to smelt for 5-30 min after the materials in the furnace are completely molten to obtain zirconia liquid, blowing and granulating the zirconia liquid by high-pressure high-temperature air, blowing the zirconia liquid into a closed space for cooling, collecting, calcining, cooling, scattering and grinding, then carrying out high-speed centrifugal spray drying, and controlling the temperature in a spray chamber to 210-270 ℃ to obtain the zirconia nanometer biological ceramic material. |
