Solubility of several transition metal chlorides (NiCl 2 , CrCl 2 , MoCl 3 , FeCl 2 ) was measured in KCl-AlCl 3 based melts. It was found that the solubility of studied metal chlorides depends on K : Al mole ratio. MoCl 3 solubility decreases with increasing AlCl 3 content. Solubility of CrCl 2 and FeCl 2 reaches maximum at K : Al ratio of 1 and decreases when this ratio either de-creases or increases. The dependence of NiCl 2 solubility on K : Al mole ratio is V-shaped with the maximum near 0.9-0.95. The effect of temperature on solubility of transition metal chlorides in KCl-AlCl3 melts was also investigated. Increasing temperature does not alter the character of «solubility – K : Al mole ratio» dependences.
