摘　　要：实验以工业用Al2O3为主要原料,在MgO-CaO-SiO2系统添加稀土氧化物La2O3和Y2O3,优化配方组成,制备出高性能的研磨介质,其氧化铝含量为98%。实验对陶瓷试样的吸水率和磨损率进行测试表征。采用XRD粉末衍射测试仪和SEM分析了试样的物相组成和显微结构。研究讨论了成形压力和烧结温度对氧化铝陶瓷性能的影响。The grinding media of the alumina content of 98% with high--performance were prepared using Commercial AlO3 as themain raw material. The additive of MgO-CaO-SiO2 system was introduced. Chemical composition was optimized via adding rare earth oxides of La2 O3 and Y2O3. The properties of the ceramic samples are investigated by measurement of water absorption and wear rate, X--ray diffraction （XRD） and scanning electron microscopy （SEM）. Forming pressure and sintering temperature on the perform- ance of alumina ceramic were discussed in this research.
