METALOTHERMIC REDUCTION OF REFRACTORY METAL OXIDES.
摘要
<p>A method of producing a refractory metal powder by (A) combining (i) an oxide particle component and (ii) a reducing agent; (B) forming a substantially uniform mixture of (i) and (ii); (C) continuously feeding the mixture into a furnace; (D) igniting the mixture at a reaction zone and starting a reaction that is sufficiently exothermic to form a high temperature flash; (E) starting a reaction that is sufficiently exothermic to form a high temperature self-sustaining flash; and (F) producing a free-flowing reduced oxide powder.</p>
