摘要
通过引入金属Ｓｉ和活性Ｃ对ＳｉＣ晶须在Ａｌ２Ｏ３－Ｃ复合耐火材料中的原位生长进行了实验研究，利用ＳＥＭ结合电子探针（ＥＰＭＡ）研究了ＳｉＣｗ在Ａｌ２Ｏ３－Ｃ复合耐火材料中的原位生长机理，提出了液－固生长机理，并讨论了其热力学和动力学条件．
In_situ growth of SiC w was formed by adding some silicon and active carbon in Al 2O 3-C refractory materials. The growth mechanism was studied by means of SEM and EPMA. A new growth mechanism, L-S(liquid-solid) mechanism, is proposed. The thermodynamic and dynamic conditions are also discussed in this paper.
