ABSTRACT:
A titanium halide and, optionally, other precursor halides compound are reduced to a predetermined titanium product, suitably at or near ambient conditions. Titanium tetrachloride, for example, 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 reaction medium, such as by application of high intensity ultrasonic vibrations or high-shear mixing to the reaction vessel. Continued cavitation of the liquid medium affects relatively low temperature reduction of the precursor halide(s) to produce a titanium-containing product such as titanium metal, a titanium alloy or compound, or a titanium matrix-ceramic composite material, or the like.
