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，能产生所谓的铝热反应。

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孔,其中微孔由微气孔微缩孔组成,物按形态尺寸分为团簇状、锥状、粒状、积聚物、丝状混合形。
