A method of bonding hard and/or soft magnetic ferrite parts comprises the steps of applying an oxide glass which contains iron oxide in an amount corresponding to about 50 to about 200% of the iron oxide proportion in the eutectic point of the respective glass-forming multi-component system, about 0.4 to about 0.8 mole percent of a wetting agent selected from the group consisting of SiO2, P2O5 and B2O3 and about 0.1 to aout 0.4 mole percent of alkali oxides BaO, SrO, CaO, K2O, Na2O and Li2O to at least one of the surfaces to be bonded together. The oxide glass may be applied prior to or after prefiring or main firing and the frit or the raw material weight-in quantity of the glass may be used. Finally, the ferrite parts are fused at temperatures in excess of the glass softening point.
