Product introduction
High purity magnesium hydroxide is produced with bischofite from Qinghai Salt Lake by synthetic method. The products produced by this method are all high-purity grade magnesium hydroxide. Which can be used to produce flame retardant, and high-purity light magnesium oxide, high-purity heavy magnesium oxide, pharmaceutical grade magnesium oxide, food grade magnesium oxide, electrical grade magnesium oxide and silicon steel grade magnesium oxide and so on. The products are preferred high-quality raw material for the production of high-end magnesium oxide. Since the successful trial production of the product in August 2006, it has been widely recognized by the market. In addition to completely replacing imported products, it has been exported to Japan, South Korea, Europe and other places. According to the needs of customers, the company can also produce high-purity magnesium oxide products, and its main content can reach 99.6% ~ 99.8%.

Product use
1. The products are mainly used as flame retardants and oil additives. They are used as raw materials for all kinds of high-purity magnesium oxide, such as pharmaceutical magnesium oxide, silicon steel grade magnesium oxide, high-purity magnesia and magnesium oxide single crystal.
2. Magnesium hydroxide, hydrochloric acid insoluble matter, water and chloride (calculated by CL) are routine inspection items. The inspection of other items is type inspection according to different uses and user requirements
