Abstract

In the manufacture of ferrites having the formula uMeO.xFe2O3 where Me is one or more divalent metals, the divalent component, wholly or partially in the form of metal, is mixed with iron oxide and heated in air, the metal being oxidized and forming a ferritic frit with the Fe2O3 during this heating process, and the frit so formed is ground and sintered to form a ferrite. In examples of Mn.Zn ferrites the initial powder mixture is heated at 1100 DEG C., ground for 14 hours in water, dried, mixed with a binder and sintered between 1260 DEG and 1430 DEG C. in N2 containing a small amount of O2 or in water vapour. Particle sizes are specified.
