Abstract: A magnetodielectric ceramic composite material comprising a first disperse phase which contains one or more magnetic ferrites, and a second, essentially continuous phase which contains electrically insulating oxides, characterized in that the electrically insulating oxides are lead(II) oxide, bismuth(III) oxide and, optionally, boron(III) oxide, is distinguished by an improved construction of the surface boundary layer. Said composite material can very suitably be used for the manufacture of frequency-selective components and wideband transmitters having a high initial permeability and a high critical frequency f.sub.0 in the range from 1 . . . 200 MHz, and for the manufacture of monolithic, multifunctional components. A description is given of a simple method of manufacturing said composite material.
