Activated magnesium oxide is an emerging magnesium salt material, which occupies an important position in magnesium oxide products. It not only requires a suitable particle size distribution, but also in the microscopic state of spherical particles or irregular particles or flake particles. The activity of magnesium oxide is affected by many factors, let's take a look at it from different aspects:
1. From the analysis of the physical properties of magnesium oxide: the activity of magnesium oxide is directly affected by its specific surface area, particle size and other factors. In general, particle size is inversely proportional to the specific surface area, that is, the smaller the particle size, the larger the specific surface area and the higher the activity.
2. Analysis from the crystallization of magnesium oxide: in general: the activity of magnesium oxide is inversely proportional to its crystallization; The more complete the crystallization, i.e. the more chemically stable it is, so the lower the activity.
3. Analysis from the material of raw materials: it is obvious that good raw materials can improve the quality of magnesium oxide, reduce impurities, and improve activity; On the other hand, the activity of magnesium oxide will also be affected by the redox reaction of the raw material during the smelting process, so choosing the appropriate reducing agent can also improve its activity.
Fourth, from the thermodynamic conditions to analyze: thermodynamic conditions mainly include pressure, temperature and atmosphere and other factors, in the preparation process of magnesium oxide, high temperature reaction can improve the activity of magnesium oxide, the choice of atmosphere will also affect the activity of magnesium oxide.
5. Analysis from the aspect of additives: adding an appropriate amount of CA, Al and other elements can trigger other reactions of magnesium, which in turn affects its oxidation reaction process, which is conducive to improving the activity of magnesium oxide.
In conclusion, many factors can affect the activity of magnesium oxide. Therefore, in the process of producing activated magnesium oxide, Tengmei and other manufacturers will comprehensively consider various factors and choose the appropriate production process to achieve the desired effect.
