The high-purity magnesium oxide produced by Hebei Messi Biology Co., Ltd. is particularly suitable for the production and manufacturing of optoelectronic glass and various mobile phone display glasses. Magnesium oxide for mobile phone glass has the characteristics of high purity, high specific gravity, few calcium and iron impurities, and low chloride content. It can be well integrated with glass components. High magnesium oxide content and few impurities are conducive to improving glass quality. The extremely low chloride content can avoid the generation of corrosive hydrogen chloride gas during heating and melting, which is conducive to protecting precision equipment from corrosion and damage.
The indicators of magnesium oxide for mobile phone glass are as follows: magnesium oxide ≥ 99%, iron oxide ≤ 0.005%, sulfur element ≤ 0.03%, chloride ion ≤ 0.05%, calcium element ≤ 0.02%, acid insoluble matter ≤ 0.05%, and heavy metal content must meet the EU ROSH standard.
Hebei Messi Biology Co., Ltd. was established in 2015 with a registered capital of 55 million yuan and is located in the High-tech Zone of Xingtai City, Hebei Province. The company’s main business is the production and research and development services of magnesium salt series products such as magnesium oxide, magnesium carbonate, magnesium sulfate, and magnesium hydroxide. The company has won many honors such as national high-tech enterprise, Hebei Province’s “specialized, refined and innovative” enterprise, and national science and technology enterprise. The products are mainly used in medicine and food, metal refining, electronic materials, rubber and plastics, composite materials, optical glass, aerospace, military nuclear industry, automotive parts, 5G new materials and other industries.
