摘要
采用控制氧化铝显微结构的方法 ,通过向氧化铝材料中引入不同粒径的板状氧化铝颗粒 ,同时采用超细粉为初始原料来改善氧化铝陶瓷的力学性能。氧化铝试样于 15 5 0℃和 16 0 0℃下烧成并加入MgO和Y2 O3 来抑制晶粒的过分长大。实验结果表明 :加入板状氧化铝颗粒后 。
The mechanical property was improved by using fine commercial alumina as raw material, controlling the microstructure Al 2O 3 and by adding in tabular alumina powders with different particle size. The samples were sintered at 1550℃ and 1600℃ respectively.MgO and Y 2O 3 were added to restrain the grain growth.The results showed that the flexural strength of the products was obviously improved.
