High purity magnesium oxide was produced by magnesium ammonium carbonate double salt process.
Given a large surplus of magnesium resources in our country at present, and the shortage of high purity magnesium oxide domestic supply situation, Hebei Meishen technology company adopted the god and the world's current limestone, dolomite whey whey method method, carbonization method, direct pyrolysis, producyion method, ammonia method of preparing principle is different, its main characteristic is simple technology, high product purity, using industrial-grade raw water magnesium chloride as raw material, magnesium salt can be obtained with MgO style 98% or higher, CaO 0.30%, or less BzO3 0.008% or less of industrial high purity low boron low calcium light magnesium oxide.
Under the same industrial conditions, light magnesium oxide containing Mg0≥ 99%, Ca0≤ 0.05% and Bz03≤ 0.005% can be produced. Other impurity indexes conform to reagent grade chemical purity.
This new process of producing high-purity magnesium carbonate and magnesium oxide at the same time can be further developed to produce special silicon steel grade magnesium oxide, magnetic magnesium oxide, medical and edible magnesium oxide and other high-value-added magnesium salt series products.
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.
