摘要： Nanometer sized particles containing titanium and platinum are prepared by a sonochemical process. Compounds of the metals are dissolved, suspended, or diluted in a low vapor pressure liquid medium, preferably at a sub-ambient temperature. A reducing gas is bubbled through the liquid as it is subjected to cavitation to affect the reductive decomposition of the metal compounds. Titanium and platinum are co-precipitated in very small particles.

摘要： 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-6A1-4V), and titanium compounds (TiSi2).
摘要翻译：在基本环境条件下将前体卤化物化合物还原成预定的产物。将卤化物加入到含有一种或多种碱金属或碱土金属作为还原剂的无水液体反应介质中。金属还原剂通过液体的空化作为非常小的小球分散在液体中，例如通过对反应容器施加高强度超声振动或高剪切混合。液体介质的持续气穴影响前体卤化物的低温还原，以产生金属，金属合金，金属化合物，陶瓷材料，金属基体陶瓷复合材料等。该实践可以例如单独或与其它氯化物一起应用于四氯化钛，以生产钛金属，钛合金（例如Ti-6A1-4V）和钛化合物（TiSi 2）。

摘要： 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.
