Hebei Messi Biology Co., Ltd. stated that silicon steel grade magnesium oxide can improve the insulation performance of silicon steel sheets, can be used as a high temperature annealing isolation agent, can also be used to make ceramic materials and electronic materials, and is used as a dephosphorization agent, desulfurization agent, and insulating coating generator
The silicon steel grade magnesium oxide industry has a good prospect Read More »
When magnesium oxide is mixed with water, the following reaction occurs: MgO+H2O=Mg(OH)2. We call this reaction the hydration of magnesium oxide. The so-called hydration rate refers to the ability of magnesium oxide to generate magnesium hydroxide. As an isolation layer before high-temperature annealing of oriented silicon steel, that is, the magnesium oxide layer, it is
