n.鋁熱劑(鋁粉焊接劑；鉛熱劑焊接法；鋁熱劑焊接法)

Microporosity in thermite weld joint consiste of blow hole and shrinkage cavities. 氧或硅含量過高形成氧化物或硅酸鹽;

Thermite is aluminum powder and a metal oxide which produces an aluminothermic reaction known as a thermite reaction. 鋁熱是鋁粉，一種金屬氧化劑，能產(chǎn)生我們所謂的鋁熱反應。

In an iron thermite reaction, iron oxide reacts with aluminum and comes out as liquid iron. 在鐵的鋁熱劑還原反應中，鐵的氧化物與鋁反應，從而生成液態(tài)鐵。

The practice shows that smelting high grade ferrotitanium with rutile by thermite method is feasible. 實踐證明，采用金紅石鋁熱法生產(chǎn)高鈦鐵在技術上是完全可行的。

A thermite reaction is initiated with some type of detonator and it can burn at temperatures of thousands of degrees. 鋁熱反應可由一些起爆劑引發(fā)，在數(shù)千度的高溫下燃燒。

In the clip above we see an attempt to “cool” the thermite reaction by dumping it in a vat of liquid nitrogen. 在上面的視頻中我們看到，為了讓鋁熱反應“降溫”而澆入大量液氮。
