To join magnetic ferrite to nonmagnetic barium titanate ceramic, a diffusion bonding process is employed. For this purpose, the samples 1 of materials to be joined are tightly wedged into a fixture 2 which may be made from a molybdenum alloy, having about 4% titanium and l% zirconium. thereby producing an extremely high pressure between the samples of material created by different thermal expansion of the materials. Ferrite wedges 3 are used between the ends of the samples and the fixture to avoid cracking at the contact areas between the fixture and the samples. Shear relief shims made of ferrite may be used to resist shear stresses.
