Low-dielectric low-high-frequency-loss LTCC material and preparation method thereof
The invention discloses a low-dielectric low-high-frequency-loss LTCC material and a preparation method thereof. The LTCC material comprises the components including borosilicate glass and calcium borosilicate glass; according to the mass percentage, the proportion of the borosilicate glass is 5%-20%, and the proportion of the calcium borosilicate glass is 80%-95%; the borosilicate glass comprises the following components in percentage by weight: 20%-50% of B2O3, 50%-85% of SiO2 and 1%-5% of alkali metal oxide, and the calcium borosilicate glass comprises the following components in percentage by weight: 30%-50% of CaO, 15%-40% of B2O3 and 20%-50% of SiO2. The required ceramic substrate is obtained through the steps of raw material mixing, glass powder smelting, glass cold quenching, crushing and grinding to form glass powder, glass powder mixing, glass powder passivating treatment, tape casting slurry preparation, tape casting, sintering and the like. The problems that dielectric constant and high frequency of an existing LTCC ceramic material of a glass ceramic system are unstable, and high-frequency loss is high are solved. The material is widely applied to the field of microwave electronic communication.
