摘要
Ａｌ添加剂在热处理过程中生成Ａｌ４Ｃ３，和ＣＯ反应生成Ａｌ２Ｏ３．与复合材料氧化过程中生成的Ｂ２Ｏ３，ＳｉＯ２形成Ｂ２Ｏ３－ＳｉＯ２─Ａｌ２Ｏ３玻璃系薄膜，有效地抑制了炭陶瓷制品中碳的氧化。
Abstract Al4C3 is formed from Al-additive in the heat treating process.Al-additive reacts with CO to'form Al2O3,and it reacts with B2O3 and SiO2,which are fomed in oxidation process,to form B2O3-SiO2-Al2O3 glassy film.The oxidation of carbon in carbon-ceramic material is intibited efficiently.
