The results show that glass ceramics with thermal expansion coefficient of 5.11×10^(-6)℃, major phase of α-cordierite and ε=5.5, tan σ=2.1×10^(-4) can be prepared by the addition of 3.6% alkalis (Li2O+Na2O), and Li2O occupies 1.8%. With Li2O substitution for Na2O, spontaneous crystallization is obviously enhanced, and temperature of the first crystallization peak decreases from 950℃ to nearly 900℃, but the crystallization temperature of the second peak was not varied. With the increase of Li2O content, mixed alkali effect can be observed from the thermal expansion coefficient and dielectric loss curve which decreases first and then increases. Dielectric constant decreases monotonously with the increase of Li2O content.
