High-strength LTCC glass ceramic material and preparation method thereof
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.
