【化】 calciothermy
“钙热法”是一个化学及冶金领域的术语,其核心含义如下:
定义
钙热法(英语:Calciothermy,法语:Calciothermie)是一种利用金属钙作为还原剂,在高温条件下还原金属氧化物的冶金工艺。该方法通过钙的强还原性提取目标金属,常用于制备高纯度金属或特殊合金。
原理
反应通式可表示为:
$$
text{M}_xtext{O}_y + ytext{Ca} xrightarrow{Delta} xtext{M} + ytext{CaO}
$$
其中,金属氧化物(MₓOᵧ)与钙在高温下发生氧化还原反应,生成金属单质(M)和氧化钙(CaO)。

钙热法(gài rè fǎ)是一种利用钙作氧化剂或还原剂的化学反应方法。在该法中,钙能够通过分解反应释放出大量热量,从而用于促进其它反应的进行。
The English translation for "钙热法" is "calcium thermite process".
The correct pronunciation for "calcium thermite process" is "kælsiəm ˈθɜːmaɪt ˈprɑːsɛs".
The calcium thermite process is used in various industries, including metallurgy and pyrotechnics. It is used as a heat source for welding, cutting and melting metals, as well as a reducing agent for metal ores.
Some synonyms for "calcium thermite process" include "thermite process" or "thermic reaction".
The antonym for "calcium thermite process" would be "exothermic process". An exothermic process releases heat instead of absorbing it the way the calcium thermite process does.
The frequency of use for "calcium thermite process" is relatively low, as it is a technical term primarily used in specialized fields. However, its synonyms, such as "thermite process" or "thermic reaction", may have greater frequency of use in scientific and industrial contexts.
