Factors Affecting the Color of Magnesium Oxide
Jun 17, 2022
We all know that magnesium oxide can be divided into heavy magnesium oxide and light magnesium oxide. Then we have also observed that the color of magnesium oxide is different, some are white, and some are light yellow, so what is the reason for the color of magnesium oxide? different?
So let me give you the answer.
The first is the ore. We know that the magnesia powder is obtained by calcining the ore, so the color of the ore itself determines the color of the magnesia powder, which basically cannot be changed.
The second is the reason for the production process of magnesium oxide. The color of light magnesium oxide is obviously different from that of heavy magnesium oxide. The color of light magnesium oxide is relatively white, and the color of heavy magnesium oxide is a little yellowish. Because heavy magnesia is obtained by calcining ores, while light magnesia is obtained by chemical synthesis. Therefore, the color will be whiter than the color of heavy magnesium oxide.
The third is the main reason: the content of silicon oxide in magnesium oxide, the higher the content of silicon oxide, the whiter the color of magnesium oxide will be. The content of normal white magnesium oxide heavy silicon oxide is generally between 5.5%-8%, and the content of yellowish magnesium oxide silicon oxide is between 2.5%-4%.
The above points are a brief introduction to the factors that affect the color of magnesium oxide. As a professional manufacturer of magnesium oxide, Qixin Magnesium Industry
