氟硅酸盐微晶玻璃的热膨胀性能主要取决于微晶玻璃的晶相组成及其相对含量．透辉石结晶相的含量增加使微晶玻璃的热膨胀系数降低，与此相反碱镁闪石结晶相的含量增加却使微晶玻璃的膨胀系数增加．K2O－MgO－SiO2－CaF2系统氟硅酸盐微晶玻璃的最小热膨胀系数为：78.4×10－7（20～300℃）；最大热膨胀系数为：85.6×10-7（20～300℃）．
The thermal expansion coefficient of fluosilicate glass-ceramics is mainly affected by the crystal phases and their amount.Diopside crystals in fluosilicate glass-ceramics tend to lower thermal expansion coefficient, while richterite crystals in fluosilicate glass-ceramics tend to increase thermal expansion coefficient.The lowest thermal edpansion coefficient of K2O-MgO-SiO2-CaF2 fluosilicate glass-ceramics is 78.4×10-7(20-300℃), while the highest thermal expansion coefficient of this glass-ceramics is 85.6×10-7(20-300℃)
