Characteristics and requirements of magnesium oxide for mobile phone glass

Hebei Messi Biology Co., Ltd. stated that at present, the LCD screens of smart tools such as mobile phones, LCD TVs, and notebook computers mainly use OLED substrate glass, and magnesium oxide plays a major role in it.

Magnesium oxide exists as an intermediate in mobile phone glass. When preparing mobile phone glass, adding magnesium oxide can control the hardening speed of the glass liquid, improve the crystallization performance, improve the melting performance of the glass, and play a role in fluxing. Prevent the glass from bursting during annealing.


By adding magnesium oxide, the viscosity of the glass can be reduced, and the diffusion rate of atoms can be increased to promote the crystallization of mobile phone glass, which has a better effect. The addition of magnesium oxide can also be combined with other substances to form magnesium silicate with low solubility, forming a dense protective film on the surface of the glass to prevent further corrosion, thereby improving the alkali resistance of the glass, so the content of magnesium oxide increases accordingly , Improved alkali resistance. Magnesium oxide can also improve the chemical stability of mobile phone glass, and at the same time, it can bring a certain hardness to the mobile phone glass, which greatly improves the drop performance of the mobile phone glass.

Hebei Messi Biology Co., Ltd. stated that the indicators for magnesium oxide used in mobile phone glass are very strict, and special attention needs to be paid to the content of iron and chloride. Excessive iron content will affect the transparency of the glass, while excessive chloride content will affect the smoothness of the glass.
