| titleOfInvention | A preparation method of zirconium-lanthanum-aluminum composite grinding medium with high toughness and high hardness |
| abstract | The invention relates to a preparation method of a high-toughness and high-hardness zirconium-lanthanum-aluminum composite grinding medium, which comprises the following steps: first mixing and stirring raw material ZrO2 powder, Al2O3 fine powder, stabilizer ① (MgO+CaO) and deionized water, After ball milling, the suspension is obtained; then the dispersant is dropped into the suspension and stirred continuously, and then the lanthanum-containing stabilizer is added to obtain the ball mill slurry after ball milling; then the ball mill slurry is press-filtered to obtain a filter cake; then calcined The calcined powder is obtained; the sintering aid and deionized water are mixed and stirred with the calcined powder, and then subjected to high-energy ball milling and granulation to obtain the granulated powder; and the sintering method is used to obtain the granulated powder after being made into a ball blank. The zirconia is stabilized by the different valence states of the composite stabilizer, combined with the sintering promotion, hardness improvement and grain boundary control of the alumina where the α phase and γ phase coexist, and the strength of the grain boundary phase is improved through solid solution and grain boundary crystallization after sintering role. Further improve the hardness, strength and fracture toughness of zirconia ceramics, and reduce wear and tear. |
