Abstract： |
The invention is a low-temperature cofired glass-ceramic combined material, based on Ba-B-Si-Ti system, adding regulating agent to reduce the sintering temperature of material to under 950 deg.C, and obtaining the glass-ceramic combined material with a dielectric constant between 4 and 50 (1GHz) and dielectric loss coefficient below 0.01. The combined material has the components in weight ratio as follows: BaO 10-30wt%, TiO2 20-60wt%, B2O3 6-10wt%, SiO2 5-50wt% and regulating agent 2-15wt%, and applies to make multilayer electronic parts, such as microwave resonators, filters, sheet inductors, capacitors, etc. |
