摘要:
Objects of the present invention are to provide a low-temperature co-fired ceramic material having a coefficient of linear thermal expansion controlled and has a high dielectric constant, and to reduce the warpage of a fired product even if it has an unsymmetrical lamination structure in a multilayer wiring board in which glass-ceramic mixed layers of different compositions are laminated. A low-temperature co-fired ceramic material in accordance with the present invention includes: SiO2—B2O3—Al2O3-alkaline earth metal oxide based glass, alumina, titania, and cordierite; glass, titania, and cordierite; or glass, titania, and mullite. When a multilayer wiring board is made of the low-temperature co-fired ceramic material, the content of cordierite or mullite of the substrate material is adjusted to control a difference in a coefficient of linear thermal expansion between the layers of the substrate material to not more than 0.25×10−6/° C.

摘要:
A composite soft magnetic material is produced from soft magnetic metal (e.g., Sendust) particles by coating the particles with a non-magnetic metal oxide (e.g., .alpha.-alumina) in a mechano-fusion manner, or heat treating the particles to form a diffusion layer of .alpha.-alumina thereon, coating the coated particles with a high resistance soft magnetic substance (e.g., ferrite), and sintering the double coated particles under pressure as by hot pressing or plasma activated sintering. It exhibits high saturation magnetic flux density, magnetic permeability, and electric resistivity. The non-magnetic metal oxide intervening between the soft magnetic metal and the high resistance soft magnetic substance is effective in reducing core loss.
