抄録

Methods to produce Ti in massive lumps by the reaction between TiCl4 and Mg are discussed theoretically and experimentally. These massive lumps were produced by a type of gaseous reaction by which the deposition of Ti was accompanied by the spontaneous ejection of the by-product MgCl2 out of the reaction system in the course of the reaction. From the preliminary experiments it was found that titanium subchlorides, TiCl3 and TiCl2, were produced if the reaction between TiCl4 and Mg vapours took place in space, but massive and compact Ti was deposited in crystalline form with a high efficiency when the mixed vapours of TiCl4 and Mg were caused to impinge and to react on the wall surfaces consisting of Ti-ribbons stretched in the reaction chamber held at 900∼950°C. The crystalline Ti deposited on the surfaces of the ribbons of Ti by these types of reactions was of a high purity and free from the by-product MgCl2 and excess Mg.
