Wear-resistant zirconium-aluminum composite ball and preparation method thereof
The invention discloses a wear-resistant zirconium-aluminum composite ball and a preparation method thereof. The wear-resistant zirconium-aluminum composite ball is prepared from alumina powder, waste fused alumina zirconia powder and a sintering aid, and comprises the following chemical components by mass: 75-90% of Al2O3, 1-15% of ZrO2, 1-6% of SiO2, 1-5% of CaO + MgO + rare earth, and 0-2% of K2O + Na2O. According to the invention, the wear-resistant zirconium-aluminum composite ball is good in wear resistance and mechanical performance, low in raw material cost and rich in raw material source, and solid waste utilization can be achieved.
本发明公开了一种耐磨锆铝复合球及制备方法，所述耐磨锆铝复合球由氧化铝粉、废锆刚玉粉和烧结助剂制成，其化学组分按质量分数计包括：Al2O375～90％，ZrO21～15％，SiO21～6％，CaO+MgO+稀土1～5％，K2O+Na2O 0～2％。所述耐磨锆铝复合球的耐磨性能和机械性能良好，原料成本低廉、来源丰富，可实现固体废弃物利用。
