【摘要】 利用Ｘ射线衍射相分析、扫描电镜（ＳＥＭ）、能谱（ＥＤＳ）分析以及化学分析等方法对铝热反应过程进行了研究，结果表明铝热反应在初期非常剧烈，后期达到平衡．铝热反应是一个复杂的反应过程，由多个具体反应组成反应初期，除ＴｉＡｌ３外，生成了亚稳态的ＴｉＡｌ９，后期ＴｉＡｌ９转化为稳定的ＴｉＡｌ３金属间化合物．更多还原

【Abstract】 An investigation was carried out of the reaction between KZTiF6 and aluminium melt. Itwas found that the reaction was very vigorous at the very beginning and then got to a dynamic equilibrium.There were several concrete reactions during the aluminothermal reaction process. At the beginning stageof the reaction, besides TiAl3, there emerged one type of metastable intermetallic phase TiA19 in aluminiummelt, which resolved lately and turned into a stable phase TiAl3.更多还原
