Abstract
A glass with high thermal expansion coefficient and excellent thermal shock resistance, wherein the glass includes the following components by mole percentage: 55-80% of SiO; 0-10% of BO; 0-10% of AlO; 2-20% of ZnO; 0-15% of MgO; and no more than 30% of LiO+NaO+KO. Through the reasonable proportioning of components, the glass has high thermal expansion coefficient and excellent thermal shock resistance at the same time. The glass is suitable for chemical strengthening, and the glass product obtained after chemical strengthening has large surface stress and large depth of stress layer.
