SPONGY TITANIUM OBTAINING METHOD Russian patent published in 2012 - IPC C22B34/12 C22B5/04 

FIELD: metallurgy.

SUBSTANCE: method involves reduction of titanium tetrachloride by means of magnesium in a vessel so that spongy titanium block is obtained, and its cleaning from impurities. Then, block is removed from the vessel, skull is separated from ball, ball is divided into upper and lower parts; and further completing of marketable batch of spongy titanium is performed. In order to obtain marketable batch of high-purity spongy titanium, upper part of ball is separated from lower part at the height of 21-35% of the ball height. Separated upper part of the ball is crushed and dissipated as to fractions, and completing of marketable batch of spongy titanium is performed using the fraction of 70+12 mm with content of the following components, wt %: nickel and chrome of up to 0.009 and iron of up to 0.025.

EFFECT: obtaining spongy titanium with decreased content of impurities, which meets the customer's requirements.
