The high purity magnesium oxide produced by Hebei Messi Biology Co., Ltd. is especially suitable for the production and manufacture of optoelectronic glass and various mobile phone screen glass. The magnesium oxide for mobile phone glass has the characteristics of high purity, high specific gravity, low calcium and iron impurities, low chlorine content, etc. It can be well integrated with the glass components, high magnesium oxide content and low impurities are good for improving the quality of glass, low chlorine content can avoid corrosive hydrogen chloride gas when heating and melting, which is good for protecting the precision equipment from corrosion damage.
Mobile phone glass with magnesium oxide indicators 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%, heavy metal content to meet the EU ROSH standards.
Hebei Messi Biology Co., Ltd. was established in 2015 with a registered capital of 55 million yuan, located in Xingdong New District, Xingtai City, Hebei Province. The main business of the company is the production of magnesium oxide, magnesium carbonate, magnesium sulfate, magnesium hydroxide and other magnesium salt series products research and development services. The company has won many honors, such as national high-tech enterprise, Hebei Province \”special precision and new\” enterprise, national science and technology enterprise. The products are mainly used in medicine and food, metal refining, electronic materials, rubber and plastic, composite materials, optical glass, aerospace, military nuclear industry, auto parts, 5G new materials and other industries.
