Electrolytic refining titanium tube technology issues

After studying the literature, we did not use a non-aqueous medium and low temperature electrolysis of aqueous medium titanium tube method. Studied only the alkali metal and alkaline earth metal chlorides and fluorides, and the dissolved salt melt titanium compound. We know that, in 600 a 900 ℃ titanium when gas elements (oxygen, nitrogen) having a high reactivity, these impurities affect the mechanical properties of metallic titanium, taking into account the impurities in the electrochemical process Basking melt transfer medium titanium tube into the possibility of precipitation on the cathode, so we set ourselves a task - to establish the cell, in this cell to be able to ensure reliable inert atmosphere and to eliminate the possibility of external impurities dirty electrolytes . In principle the use of certain widely used in modern technology, we are in the future and how long the test after a long search, the design and manufacture of a large-scale experimental device, which can solve the problems in the purity titanium electrolysis using the relevant type electrolyte melt. In this device all determine titanium electrolysis process planning major test tube. Only in individual cases, in order to identify some of the problems, and only then move to a small laboratory test device.
    In order to select an electrolytic refining process of titanium, titanium test various compounds. Electrolysis of titanium trichloride, titanium tetrachloride, titanium potassium fluoride and titanium dioxide.
    Titanium trichloride having high solubility in the alkali metal chloride electrolyte into the shaped body. When the melt lift trichloride concentration - the timing of the electrolysis; cathodic electrolysis on the metal precipitated titanium, and deposited on the anode chlorine, of titanium ingot taken out from the electrolytic cell, and chlorine is here and after hydrogen supplied to the anode combine into hydrogen chloride.
    Because in the high-temperature electrolysis hydrogen bad, so start looking for other low-cost method of producing chloride in the melt. Has determined that if the current through the graphite tube along, through the graphite tube steam supply TiCli, the current can disintegration of titanium tetrachloride reduction.
