| description | The invention discloses a low temperature co-fired ceramic material with a high bending strength. The material comprises 40-50 wt% of a glass ceramic and 50-60 wt% of alumina; and the glass ceramic comprises 5-40 wt% of calcium carbonate, 5-40 wt% of boric acid, 1-10 wt% of magnesium carbonate, 1-15 wt% of zirconium oxide, 5-20 wt% of zinc oxide and 15-50 wt% of silicon oxide. The calcium carbonate, boric acid, magnesium carbonate, zirconium oxide, zinc oxide and silicon oxide synergistically promote each other to produce the glass ceramic with a high viscosity. The low temperature co-fired ceramic material is prepared by melting the glass ceramic and alumina. The material can be sintered at 860 DEG C for 15 min to obtain the best density, and the obtained ceramic material has a bending strength of above 350 MPa, and can effectively improve the impact resistance of elements; and the ceramic material also has good microwave electrical properties, and the dielectric constant is about 8.0and the dielectric loss |
