Filed: 1974-08-26
Abstract: Ti is prepd. by pouring Mg and TiCl4 into the redn. appts. to produce Ti mixed with such by-prods. as Mg and MgCl2. The by-prods. are removed from the Ti in a vacuum sepn. appts. by heating the products of reaction to temp. above 900 degrees C sublimating the Mg and MgCl2 fluid during the vacuum sepn. and sprinking cooling directly over the condenser within the period when a temp. above 900 degrees C is reached and the most violent sublimation of the Mg and MgCl2 occurs. The degree of its cooling by sprinkling is controlled in accordance with the surface temp. of the condenser is cooled with a liq. which is collected in the space between the walls of the condenser and jacket. Used to produce spongy Ti for subsequent use in prodn. of Ti alloys. The method allows the intensity of cooling the condenser of the vacuum sepn. appts. to be controlled during violent sublimation of Mg and MgCl2 making it possible to speed up the heating of the reaction mass and to reduce the duration of vacuum sepn. A dense non ignitable condensate of Mg is produced, thus stepping up the efficiency of the equipment, reducing the amt. of labour required and allowing the Mg condensate to be effectively used in the subsequent working cycle of the redn. appts.
