  • Patent number: 8876938
    Abstract: The present invention provides a process for producing sponge titanium, which includes the following steps: Step A: placing aluminum into a resistance furnace, vacuum pumping, introducing inert gas, heating to molten aluminum; Step B: opening a reactor cover, adding a proper amount of potassium fluotitanate to a reactor, leakage detecting after closing the reactor cover, slowly raising the temperature to 150° C., vacuum pumping, and continuously heating to 250° C.; Step C: introducing inert gas into the reactor, continuously raising the temperature to 750° C., stirring uniformly; Step D: opening a valve to adjust the stirring speed, adding molten aluminum drops, and controlling the reaction temperature to 750° C. to 850° C.; Step E: opening the reactor cover, removing a stirring device, eliminating the upper layer of KAlF4 to obtain sponge titanium. The present invention has the beneficial effects of short process flow, low cost, environmental protection and harmlessness.

  • Patent number: 8834601
    Abstract: A method for producing a titanium-aluminum alloy containing less than about 15 wt. % aluminum, comprising: a first step in which an amount of titanium subchlorides at or in excess of a stoichiometric amount required to produce the titanium-aluminum alloy are reduced by aluminum to form a reaction mixture comprising elemental titanium, and then a second step in which the reaction mixture comprising elemental titanium is heated to form the titanium-aluminum alloy, whereby reaction kinetics of the method are controlled such that reactions resulting in formation of titanium aluminides are minimized.

  • Patent number: 5958106
    Abstract: A method of producing a non-metal element or a metal or an alloy thereof from a halide or mixtures thereof. The halide or mixtures thereof are contacted with a stream of liquid alkali metal or alkaline earth metal or mixtures thereof in sufficient quantity to convert the halide to the non-metal or the metal or alloy and to maintain the temperature of the reactants at a temperature lower than the sintering temperature of the produced non-metal or metal or alloy. A continuous method is disclosed, particularly applicable to titanium.

  • Patent number: 5779761
    Abstract: A method of producing a non-metal element or a metal or an alloy thereof from a halide or mixtures thereof. The halide or mixtures thereof are contacted with a stream of liquid alkali metal or alkaline earth metal or mixtures thereof in sufficient quantity to convert the halide to the non-metal or the metal or alloy and to maintain the temperature of the reactants at a temperature lower than the lesser of the boiling point of the alkali or alkaline earth metal at atmospheric pressure or the sintering temperature of the produced non-metal or metal or alloy. A continuous method is disclosed, particularly applicable to titanium.
