Pilot plant studies on the production of ductile titanium sponge from pure titanium tetrachloride

Technical Report:

Abstract

Three different routes were examined, namely: (i) magnesium reduction and pyro-vacuum treatment, (ii) magnesium reduction and acid leaching, and (iii) two-stage reduction with sodium, followed by aqueous processing. Magnesium- reduced and vacuumtreated titanium sponge was of uniformly good quality, contained less than 1000 ppm oxygen, and corresponded to a button hardness of 90 to 100 VPN. Acid-leached sponge from magnesium reduction had a relatively higher oxygen content (l000 to 1500 ppm), but was still of acceptable quality (hardness 125 VPN). A significant portion of the metal from sodium reduction was in the form of shiny crystals, of very low button hardness (60 to 90 VPN). The operations established the satisfactory performance of the various equipment designs and also the optimum process conditions. (auth)
