High Purity Magnesium Hydroxide 99%

We are offering high purity magnesium hydroxide 99%.
Introduction
high purity magnesium hydroxide uses the bischoffite from the qinghai salt lake as the raw materials, produced by the synthesis method. The products made by this method are all the high purity grade and can not only be used in the production of flame retardants, but also the raw materials of producing high purity light magnesium oxide, high-purity heavy magnesium oxide, pharmaceutical grade magnesium oxide, food grade magnesium oxide, electrical grade magnesium oxide, silicon steel magnesium oxide and other high quality magnesium oxide etc.
Since the trial produce were succeed and achieved widespread recognition in the market in august 2006, the high purity magnesium hydroxide can completely substitute the import products, the main content can attain to 99.6% to 99.8%. It has been exported to japan, korea and europe etc.
Application
1. The high purity magnesium hydroxide is mainly used for flame retardant and oil additives. It can also be used in high purity magnesia as the raw materials such as medicine grade magnesium oxide, silicon steel magnesium oxide, high purity magnesia and single crystal magnesium oxide etc.
2. The routine inspection items are magnesium hydroxide, hydrochloric acid insoluble, water and chloride (cl). The other types of inspection are depending on the different applications and customers requirements.
