研究了铅硅玻璃在堇青石基微晶玻璃烧结中的作用及其添加量对微晶玻璃性能的影响．结果表明：铅硅玻璃的加入可以促进微晶玻璃的烧结致密化；随着铅硅玻璃加入量的增加，烧结样品的介电常数亦增加，且与密度变化曲线相似；微晶玻璃烧结样品的热膨胀系数符合加和性规律．
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.
