摘　　要：以氧化铝陶瓷作为基质材料,通过向氧化铝材料中添加纳米氧化铝粉,同时添加α型氧化铝板晶颗粒来改善氧化铝陶瓷的力学性能.试样在1 650℃温度下烧成,并加入La2O3、MgO等氧化物降低烧成温度.试验表明:添加纳米氧化铝粉和α型氧化铝板晶颗粒后,材料的强度和韧性得到明显提高.Taken the alumina ceramics as basic materials , the mechanical property was improved by using α - tabular alumina powders and nanometer alumina powders. The samples were sintered at 1 650 ℃. La2O3 and MgO were added to reduce the sintering temperature. The results showed that the toughness and the flexural strength of the products were obviously improved.
