Effect of Leadsilicate Glass on Properties of Cordierite-based Glass Ceramics

Various contents of leadsilicate glass were used to observe the effect on the sintering and properties of cordierite-based glass ceramics. The results show that leadsilicate glass can enhance densification of cordierite glass. The dielectric constant increases with the addition of leadsilicate glass, and its curve similar to the density curve. The thermal expansion coefficients of the samples with different leadsilicate glass contents exhibit the characteristic of additivity.
