Abstract
A glass ceramic substrate contains a glass ceramic having a compressive stress layer on a surface thereof and a crystalline phase containing LiAlSiO, quartz, and quartz solid solution. The glass ceramic has 60 to 80% of SiO, 4 to 20% of AlO, more than 0 but less than or equal to 15% of LiO, more than 0 but less than or equal to 12% of NaO, 0 to 5% of KO; more than 0 but less than or equal to 5% of ZrO, 0 to 5% of PO, and 0 to 10% of TiO. The quartz and the quartz solid solution crystalline phase account for 15 to 30% of the glass ceramic by wt %, the LiAlSiOcrystalline phase accounts for not greater than 15% of the glass ceramic by wt %, and a ratio of ZrO/LiO is more than 0 but less than or equal to 0.35.
