Expound magnesium metallurgy with ferrosilicon process and calcium metallurgy with aluminothermic process by contracting technological conditions.

通过工艺条件对比分析,阐明了法炼镁与铝法炼钙者工艺过程、设备条件相同。

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

铝是铝粉，一种金属氧化剂，能产生我们所谓的铝反应。
