  • Method of producing titanium from titanium oxides through magnesium vapour reduction
    Patent number: 10316391
    Abstract: Disclosed herein is a novel approach to the chemical synthesis of titanium metal from a titanium oxide source material. In the approach described herein, a titanium oxide source is reacted with Mg vapor to extract a pure Ti metal. The method disclosed herein is more scalable, cheaper, faster, and safer than prior art methods.
    Type: Grant
    Filed: August 2, 2016
    Date of Patent: June 11, 2019
    Assignee: Sri Lanka Institute of Nanotechnology (PVT) Ltd.
    Inventors: Gayani Abayaweera, Gehan Amaratunga, Niranjala Fernando, Veranja Karunaratne, Nilwala Kottegoda, Ruwini Ekanayake
  • METHOD OF PRODUCING TITANIUM FROM TITANIUM OXIDES THOUROUGH MAGNESIUM VAPOUR REDUCTION
    Publication number: 20180223393
    Abstract: Disclosed herein is a novel approach to the chemical synthesis of titanium metal from a titanium oxide source material, such as a mineral comprising titanium. In the approach described herein, a titanium oxide source is reacted with Mg vapor to extract a pure Ti metal.
