A method for producing a metal powder includes maintaining molten reducing metal in a sealed reaction vessel that is substantially free of oxygen and water, establishing a vortex in the molten reducing metal, introducing a metal halide into the vortex so that the molten reducing metal is in a stoichiometric excess to the metal halide, thereby producing metal particles and salt, removing unreacted reducing metal, removing the salt, and recovering the metal powder. The molten reducing metal can be a Group I metal, a Group II metal, or aluminum.
一种生产金属粉末的方法,包括在密封的反应容器中维持熔融的还原金属,该容器基本上不含氧和水,建立熔融还原金属中的涡流,在涡流中引入金属卤化物,使熔融还原金属的量超过金属卤化物的量,从而产生金属颗粒和盐,去除未反应的还原金属,去除盐,并回收金属粉末。熔融还原金属可以是第一组金属、第二组金属或铝。
