Abstract

A process for shaping Ferrite products comprising mixing 50 to 80% finely divided ferrite powder with at least 1.7% of the combination of an epoxy resin together with an epoxy resin activator and a quantity Sufficient compatible organic liquid for viscosity control so that it gives the liquid composition a resulting viscosity of 20,000 to 80,000 centipoise at 25ºC, transferring the liquid composition to a substrate surface having a desired shape, curing the composition to cause it to Cure the epoxy resin, separate the article from at least the surface of the substrate and gradually heat the article to a temperature above 600ºC to remove the binder, and then heat the article to the sintering temperature of the ferrite for a period enough to provide the desired magnetic properties.
