High pure magnesium oxide refers to the content of MgO reached more than 98%. And the active magnesium oxide refers to the ability to participate in physical or chemical process, the different activity mainly depends on the size of the magnesium oxide crystallite, incomplete structural and other factors.
The applications of pure magnesium oxide.
Under the condition of high temperature, high pure magnesium oxide has excellent electrical insulation, alkali resistance, and good light permeability, often be used as high temperature materials. Meanwhile, it can be used as the raw materials of high pure fused magnesia. Act as “AR magnesium oxide” in chemical. In the electric field, used for insulating material & magnetic device filler, and a variety of carriers. In the field of ceramic, used in the manufacture of raw materials, such as transparent ceramic crucible and substrate.
What are the difference between the high pure magnesium oxide and active magnesium oxide? In the process of production of high-grade products, need to add the high pure and low impurity magnesium oxide. But if you want to improve the reaction speed, active magnesium oxide is need. In general, active magnesium oxide reaction speed is faster. The application of active magnesium oxide is widely. According to the different iodine value, active magnesium oxide can be divided into low active, active, highly active. Low active magnesium oxide is mostly used for flue gas desulfurization, acidic waste water treatment, etc. Medium active magnesium oxide is mainly used for neoprene. Highly active magnesium oxide is mainly used for medical butyl rubber bottle stopper. Besides, Low active magnesium oxide generated made by calcining magnesite, the active magnesium oxide that iodine absorption value more than 120 built/g is usually produced by a special process.
