The new synthetic technology of high purity magnesium oxide

After ten years of research, we recently developed can be used as a new technology for chemical industry and can be used as a metallurgical light high purity magnesia magnesia pre plant a magnesium ammonium carbonate salt method.

Electrical grade magnesium oxide, magnesium oxide powder factory in our country and a large surplus of magnesium resources, high purity MgO serious shortage of domestic supply, the production principle is not the same with the current method of limestone and dolomite, WHEY WHEY carbonization, direct pyrolysis, ammonium bicarbonate and ammonia method and so on, the the main feature is the simple process, high product purity, using industrial grade crude water magnesium chloride as magnesium salt raw materials, electrical grade magnesium oxide, 97 fused magnesia, 98 fused magnesia can be prepared with MgO = 98%, CaO = 0.30%, BzO3 = 0.008%, the industrial high purity low boron low calcium light Magnesium Oxide. In the same industrial conditions, the Saline Lake Qinghai potash plant by-product magnesium chloride as magnesium salt raw materials, can be prepared with Mg0 = 99%, Ca0 = 0.05%, B = 0.005% z03 industrial ultra pure boron free low calcium light Magnesium Oxide. Other impurity indexes accord with reagent grade chemical purity. This new technology and production of high purity magnesium carbonate and Magnesium Oxide, further development can also produce special silicon steel grade Magnesium Oxide, market price 2.5, 28 thousand yuan / ton; magnetic Magnesium Oxide, the market price by 15 thousand yuan / ton; medical and edible Magnesium Oxide, the market price of 38 thousand yuan / ton; medical and edible magnesium hydroxide, the market price. 15 thousand yuan / ton, the high added value of magnesium salt products.
