METHOD OF OBTAINING SPONGY TITANIUM AND DEVICE FOR ITS REALISATION Russian patent published in 2015 - IPC C22B34/10 C22B5/04 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to obtaining spongy titanium by the thermal reduction of titanium tetrachloride with liquid magnesium. The device contains a retort with a false bottom, provided with a cover with the central fitting pipe and a fitting pipe for argon supply, a discharge device, and a reaction chamber. The reaction chamber is located in the retort below the level of magnesium filling, is rigidly fixed from the bottom to the pipe, installed in the central fitting pipe and provided with fitting pipes for the supply of titanium tetrachloride and argon into the reaction chamber. The reaction chamber consists of the upper cylindrical part with side slots and attached to it lower part, made in the form of open from the bottom chutes with narrowed to the bottom walls and transverse partitions, rigidly connecting the chute walls. In accordance with the method the retort is vacuumed, filled with argon and simultaneously heated, liquid magnesium is poured into the reaction chamber, argon is supplied to a pressure by 20-40 gPa higher than the pressure in the retort, and titanium tetrachloride, and reduction with the accumulation of spongy titanium on the false bottom is carried out at a reduction rate higher than the rate of titanium tetrachloride supply in the reaction chamber with the formation of own pressure fluctuations in the gas volume of the reaction chamber.

EFFECT: increased quality of the reaction mass is ensured.
