Barium ferrite glass-ceramic

Production. There are three important methods for manufacturing barium ferrite on an industrial scale the ceramic, hydrothermal, and glass crystallization methods. The main producers are Toshiba and Toda. 

Barium Carbonate. BaC03, decomposes at 1450°C sp. gr. 4.4. Occurs naturally in Durham, England, as witherite. The principal use in the ceramic industry of the raw material is for the prevention of efflorescence on brickwork for this purpose it is added to brick-clays containing soluble sulphates. The pure material is used in the manufacture of barium ferrite permanent magnets, and in some ceramic dielectrics to give lower dielectric loss. In the glass industry this compound is used in optical glass and television tubes it is also used in some enamel batches.
