Abstract — The reaction of titanium with fused mixtures based on sodium hydroxide and various salts (sodium nitrate and nitrite, sodium and potassium chlorides, sodium orthophosphate, sodium meta- and orthotitanates, potassium oxyfluoride and hexafluorotitanate) is studied. The mechanism of inhibiting the corrosion of the studied metal in ionic melts that involve oxidants and titanium salts is discussed.
