The magnesium oxide has many characters: in the activity, crystal texture and size distribution, the magnesium oxide is different from many products. These characters are the key factors to affect the product quality. At first, we talk about the activity of magnesium oxide. In order to improve the reaction capacity between magnesium oxide and silicon dioxide. The magnesium oxide must have activity. The nano magnesium oxide has the largest reactivity.
Therefore, introducing nano magnesium oxide particle to silicon steel grade magnesium oxide through nanotechnology, it can improve the reactivity silicon steel grade magnesium oxide. When coating the magnesium oxide particle on the surface of silicon steel sheet, it can verge to the closest packing. (reducing the void content between magnesium oxide and the surface of steel disc, it can improve the density of Mg2SiO4)
