Y_2O_3-Al_2O_3-SiO_2添加剂在低温烧结SiC中的作用

THE EFFECT OF Y_ 2O_ 3-Al_2O_ 3-SiO_2 ADDITIVES IN LOW-TEMPERATURE SINTERING OF SILICON CARBIDE

本文探讨了Ｙ２Ｏ３ － Ａｌ２Ｏ３ 添加剂在低温无压烧结ＳｉＣ 中的作用以及在Ｙ２Ｏ３ － Ａｌ２Ｏ３ 添加剂中引入ＳｉＯ２ 的作用及机理，从而阐明了通过多项合理、有效复合添加降低ＳｉＣ

The role of Y 2O 3-Al 2O 3 additives in low-temperature pressureless sintering of silicon carbide was investigated.The effect of SiO 2 introduced into Y 2O 3-Al 2O 3 additives was discussed.The results showed that it was possible to cut down the sintering temperature of silicon carbide by rational multiphase additives.
