Thermite is aluminum powder and a metal oxide which produces an aluminothermic reaction known as a thermite reaction.

铝热是铝粉，一种金属氧化剂，能产生我所的铝热反应。

The practice shows that smelting high grade ferrotitanium with rutile by thermite method is feasible.

实践证明，采用金红石铝热法生产高铁在技术上是完全可行的。

The pattern of fracture by impact penetration test and tensile fatigue test of thermite welding with stereoscan was observed,and the component of defect with energy spectrum was analyed.

微观缺陷主要包括微杂,其中微由微气微缩组成,杂物按形态尺寸分为团簇状杂、锥状杂、粒状杂、积聚物杂、丝状杂混合形杂。
