Magnesium chloride is one of the rich and high added value substances in brine. In addition to its own use value, magnesium chloride as the raw material to produce other magnesium products also have a very wide range of applications. High purity magnesium oxide is one of them.

Currently, there are many methods to produce high-purity magnesium oxide, and the pyrolysis of magnesium chloride is one of the most popular methods in recent years. In particular, it is the best choice for many enterprises to try to put into mass production due to its advantages of no additives, low production cost, no pollution to the environment and simple process. In this paper, high quality hexahydrate magnesium chloride crystals were prepared from bromine production waste liquid provided by hangu salt farm.

Magnesium oxide products with high purity and stable properties were prepared by the pyrolysis method of magnesium chloride. The technological parameters of preparing high purity magnesium oxide were studied in three parts. n the pyrolysis stage of magnesium chloride, the effects of pyrolysis time and pyrolysis temperature on the purity, activity and decomposition rate of magnesium oxide were investigated, and the relationship between the activity of magnesium oxide and its microstructure was discussed. The results showed that with the increase of temperature and pyrolysis time of magnesium chloride, the purity and decomposition rate of magnesium oxide increased, the activity of magnesium oxide decreased and the grain size increased.

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.
