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

通过工艺件比分析,阐明了硅热法炼镁与铝热法炼钙者工艺过程、设备件基本相同。

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

铝热是铝，金属氧化剂，能产生我们所谓的铝热反应。
