1. produce a method for titanium metal, the method comprises:

  • By mixing TiO 2form non-sintered electrode with carbon, and there is no heated under air to 1000-2200 DEG C, continue 0.1-100 hour, form titanium suboxide/carbon composite anode, The anode that electrochemical dissolution is formed by described titanium suboxide/carbon composite in molten salt electrolyte, andAt negative electrode, the titanium suboxide of dissolving is reduced to titanium metal, wherein, ionogen is selected from the eutectic mixture of sodium-chlor, lithium chloride and Repone K;

    Described titanium suboxide is the compound that at least one is selected from lower group;

    Ti 2o 3, Ti 3o 5and Ti 4o 7.
