Method for the production of alkaline-earth ferrites and lead ferrites for memory cores

摘要

Platelike alkaline-earth ferrites and lead ferrites for memory cores are produced from impure initial substances by decomposing the initial substances with a molten, basic alkali compound, and the precursor separated off after dissolution in water is annealed for 0.5 to 6 hours at 600 DEG to 950 DEG C.
