| 摘 要： | 本文采用反应结合制备方法，通过对坯体进行预氧化使ＳｉＣ颗凿表面氧化形成ＳｉＯ２，而后在烧成中与添中剂ＡＩ２Ｏ３－Ｙ２Ｏ３反应，使坯体气化率减少，制备了多孔ＳｉＣ基陶瓷。文章探讨了坯体中ＳｉＣ的氧化特征、反应结合过程和相变化以及它们对烧结体性能的影响。

| Abstract: | Silicon carbide was prepared by using reaction-bonding mechanism. SiO2 on the surface of SiC powder derived for pre-oxidation of green body would react with Al2O3/Y2O3. This process could reduce the porosity while sintering. Oxidation chaxacteristic of SiC, process and mechanism of reaction-bonding and their effect on properties of sintered body were investigated. |
