The high purity magnesium oxide produced by Hebei Meishen Technology Co., LTD is especially suitable for the production and manufacture of photoelectric glass and various kinds of mobile phone screen glass.

Meishen make business with CORNING Company,Now the mobile phone is basically a hand, some business more busy people, even have two or three mobile phones, but we have noticed the phone glass and ordinary glass what is the difference.

A chemical called magnesium oxide is used in the glass of mobile phones, so what does magnesium oxide do?

Mobile phone glass magnesium oxide has high purity, less than significant, calcium iron impurities, chlorine root content is low, may well and the integration of glass components, high content of magnesium oxide impurities to improve glass quality, less chlorine content is extremely low to avoid the heat generated when the molten corrosive gas, hydrogen chloride is helpful to protect precision equipment from corrosion damage.

The indicators of magnesium oxide for mobile phone glass are as follows: magnesium oxide ≥99%, iron oxide ≤0.005%, sulfur element ≤0.03%, chlorine root ≤0.05%, calcium element ≤0.02%, acid insoluble substance ≤0.05%, and heavy metal content shall comply with THE EU ROSH directive.

Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.

　　Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.

　　Hebei Meishen Chemical Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.

　　With rich experience in the research, development, production, management and operation of magnesium oxide products, Meishen Group has always attached great importance to the research and development of new products and strict requirements on product quality. Meishen has a high-level sales team. The business covers more than 20 countries and regions around the world. It is widely welcomed by new and old customers.
