Abstract
A method is disclosed for the manufacture of particles composed of an intimate admixture of barium or strontium ferrite and ferric oxide from a chloride solution containing barium or strontium ions and ferrous ions by a pyrohydrolysis reaction. The presence of carbon dioxide in the heated atmosphere in which pyrohydrolysis of an admixture of alkaline earth metal chloride and iron chloride is carried out has been discovered to substantially decrease the temperature required for reaction to occur.
