In the paper presents the process of producing glass ceramics based on corundum modified with borosilicate glass with various additives. The described Al2O3/SiO2–B2O3–CaO–MgO–Na2O–K2O system has developed for LTCC technology and got a sintering temperature less than 950 ?. The influence of additive content on the sintering temperature, microstructure, ceramic and electrophysical properties of ceramics has been investigated. Developed composition has a dielectric constant of ?r = 6.73…6.82 and tangent of the dielectric loss angle tg ? = 8.0…8.6?10–3 at a frequency f = 1 MHz.
