  TiCl₄ (Ti⁴⁺) is reduced under H₂ atmosphere with a tungsten wire. The TiCl₄ (liquid) is heated up to evaporate it. At the same time a potential is applied to heat the wire. As soon as the TiCl₄ in the gas phase gets in contact with the wire it is reduced to generate TiCl₃ (purple powder).
   
  TiCl₄ +  H₂  =  TiCl₃+ HCl
