Patent ID: 10160689

Abstract:
Disclosed is a CBS-based low-temperature co-fired ceramic (LTCC) material, and a preparation method thereof. The material has, as a main component, a sintered phase of low dielectric constant of CaSiO3 and CaB2O4, and comprises CBS and a dopant. The CBS comprises, by weight, 30-40% of CaO, 15-30% of B2O3, and 40-50% of SiO2, and the dopant comprises 0-2% of P2O5, 0-2% of nanometer CuO, and 0.5-2% of nanometer V2O5. The preparation method comprises mixing oxides including a CBS-based dielectric ceramic as a base and one or two of P2O5 and CuO as an initial dopant, and then adding V2O5 as a final sintering aid, to prepare the material. In the present invention, a CBS-based LTCC material that is obtained by sintering at a low temperature and has the advantages of low dielectric constant, low loss, and good overall performance is provided.
