ABSTRACT:
Disclosed is a novel ceramic-glass composite material useful as a material of electronic parts for attenuation of noise components in the GHz range. The composite material is a sintered body obtained by a heat treatment of a powder blend consisting of 35-55% by weight of a hexagonal ferrite of the formula Ba.sub.3 M.sub.2 Fe.sub.24 O.sub.41 (M.dbd.Co, Ni and/or Zn) and the balance of a glass material consisting of SiO.sub.2, Al.sub.2 O.sub.3, SrO, CaO, MgO and B.sub.2 O.sub.3, of which the content of SrO is 15-25% by moles, at a relatively low sintering temperature of 850-920 .degree. C. for 10-30 minutes.
