ABSTRACT:
A precursor halide compound is reduced to a predetermined product at substantially ambient conditions. The halide is added to an anhydrous liquid reaction medium containing one or more alkali metals or alkaline earth metals as reductants. The metal reductants are dispersed as very small globules in the liquid by cavitation of the liquid, such as by application of high intensity ultrasonic vibrations or high-shear mixing to the reaction vessel. Continued cavitation of the liquid medium affects low temperature reduction of the precursor halide(s) to produce a metal, metal alloy, metal compound, ceramic material, metal matrix-ceramic composite material, or the like. The practice may be applied, for example, to titanium tetrachloride, alone or with other chlorides, to produce titanium metal, titanium alloys (for example Ti-6Al-4V), and titanium compounds (TiSi2).
