Low-dielectric low-loss Ba-Si-B-M-based LTCC material and preparation method thereof

Abstract

The invention belongs to the field of electronic information ceramics and manufacturing thereof, and particularly relates to a low-dielectric low-loss Ba-Si-B-M-based LTCC (Low Temperature Co-Fired Ceramic) material and a preparation method thereof. The compact Ba-Si-B-M-based microwave ceramic material is sintered and molded at the low temperature of 850-950 DEG C by adjusting the formula of the Ba-Si-based ceramic raw materials and adopting a solid phase method by fully utilizing the characteristic that the lattice energy of Si-O bonds is high due to the fact that Si < 4 + > ions are low in polarizability and the covalent bonding property of the Si-O bonds in the complex chemical bond theory. A eutectic compound is formed in the sintering process, so that grain rearrangement is promoted, and BaSi2O5 phase ceramic is separated out along with sintering; the low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low-dielectric-constant low
