Abstract

The invention relates to a high-strength LTCC glass ceramic material and a preparation method thereof, the LTCC glass ceramic material comprises the following components in percentage by mass: lead borosilicate glass and aluminum oxide, the weight of the lead borosilicate glass is 2%-10% of that of the aluminum oxide, and the lead borosilicate glass comprises the following components in percentage by mass: 10%-40% of PbO, 2%-15% of B2O3, 50%-85% of SiO2, 2%-15% of CaO, 0.5%-5% of Al2O3 and 1%-5% of alkali metal oxide; and the aluminum oxide is alpha-Al2O3. The high-strength LTCC glass ceramic substrate is obtained through the steps of raw material preparation, raw material mixing, glass powder smelting, glass cold quenching, crushing and grinding, aluminum oxide powder glass modification, modified aluminum oxide powder preparation, glass-ceramic mixing, tape casting slurry preparation, tape casting, sintering and the like. The problem that existing glass ceramic is not high in strength is solved. The material is widely applied to the field of microwave electronic communication.

Description

technical field [0001] The invention belongs to the field of electronic components, specifically, to the field of microwave electronic components, and more specifically, to the field of ceramic materials for microwave electronic components. Background technique [0002] At present, high-strength LTCC materials are mainly glass or glass-ceramics added with ceramic phase reinforcement to obtain high-strength LTCC materials. Among the LTCC materials of the glass-ceramic system, alumina is a very high-strength material, so the short board that determines the strength of LTCC materials is the strength of the glass. The more stable the network structure of the glass, the higher the strength of the glass. Glass and alumina The better the wettability of the glass, the better the interface contact between glass and alumina, the higher the structural strength of the LTCC material, and the smaller the loss of home appliances during high-frequency use.
