  • Patent number: 9567690
    Abstract: The invention provides a process for the production of crystalline titanium powder containing single crystals or agglomerates of single crystals having an average crystal size (by volume) greater than 1 ?m, said process including reacting a titanium chloride species, preferably titanium dichloride, and reducing metal in a continuous back-mix reactor to produce a free flowing suspension of titanium powder in molten chloride salt wherein: i. both the titanium chloride species and the reducing metal are dissolved in a molten chloride salt and fed to the reactor containing a chloride salt of the reducing metal; ii. the average feed ratio of the titanium chloride species and reducing metal to the continuous back-mix reactor is within 1%, preferably within 0.1%, of the stoichiometric ratio required to fully reduce the titanium chloride salt to titanium metal; iii.
    Type: Grant
    Filed: May 29, 2013
    Date of Patent: February 14, 2017
    Assignee: CSIR

  • Patent number: 9017625
    Abstract: A method of upgrading a titaniferous material includes nitriding and reducing a titaniferous material which includes TiO2 and Fe oxides in the presence of nitrogen and carbon to convert the TiO2 to TiN and to reduce most of the Fe oxides to Fe. The Fe is oxidized in preference to the TiN to form Fe2+ ions, whereafter the Fe2+ ions are removed to produce an upgraded low-Fe TiN bearing material.
