Did you know?
Metallothermic reduction is a general term for reduction reactions conducted to obtain a target metal or compound from feed material such as oxides or chlorides (halides) by using a metal as a reducing agent. Many reactive metals such as Ti, tantalum (Ta), and REMs are produced by metallothermic reduction. WebHunter process Metallothermic reduction of chlorides has been the basis of some very important processes for reactive metals production. Examples include the Kroll and Hunter processes for the preparation of zirconium and titanium, and calcium or lithium reduction processes for the rare earths. Main uses ofNa alloys.
