METHOD OF HYDROLYZING METAL HALIDES

摘要

A process relating to the hydrolysis of metal halides and their production of corresponding metal oxides by the hydrolysis of their chlorides and the calcining of the hydrolysis product is disclosed. Novel aspect including obviating the neutralizing step for the hydrochloric acid by using ammonia and disposing of the resulting ammonium chloride and the two step addition initially of metal halides to water until there is no observable positive heat of reaction and then adding the metal halide in amounts up to the stoichiometric quantity for the hydrolysis product obtained.
