Active magnesium oxide is one of the magnesium oxide series products. However, some of the index requirements between the two are different. Active magnesium oxide requires a suitable particle size distribution, and the microscopic morphology is irregular particles or nearly spherical particles or flaky crystals. There are many factors that affect the activity of magnesium oxide. Next, we will analyze it in detail from several aspects:
1. Physical properties of magnesium oxide
The physical properties of magnesium oxide such as particle size and specific surface area directly affect its activity. Generally speaking, the smaller the particle size and the larger the specific surface area, the larger the contact area with other substances, and the higher the activity.
2. Crystallization of magnesium oxide
In general, the more complete the crystallization of magnesium oxide, the lower the activity. The more complete the crystallization, the fewer defects, the more stable the chemical properties, and the lower the activity.
3. Quality of raw materials
The quality of raw materials also has a very obvious effect on the activity of magnesium oxide. High-quality raw materials can improve the purity of magnesium oxide and reduce the presence of impurities, so it has better activity. At the same time, the redox reaction during the raw material smelting process will also affect the activity of magnesium oxide. Selecting a suitable reducing agent can promote the oxidation reaction and improve the activity of magnesium oxide.
4. Thermodynamic conditions
Thermodynamic conditions are also one of the important factors affecting the activity of magnesium oxide! It includes temperature, pressure and atmosphere. For example, when preparing magnesium oxide, high temperature reaction can promote the formation of magnesium oxide and improve its activity. Not only that, the choice of atmosphere will also affect the process of oxidation reaction, thereby affecting the activity of magnesium oxide.
5. Additives
The activity of magnesium oxide is also affected by additives. For example, adding a certain amount of elements such as Al and Ca can cause magnesium to react with other elements, thereby changing the process of oxidation reaction and improving the activity of magnesium oxide. In addition, magnesium oxide can be dispersed in it using a suitable carrier to increase its surface area and prevent agglomeration, thereby improving the activity of magnesium oxide.
6. Activator
In the process of preparing magnesium oxide, adding some compounds such as K2O, Na2CO3, MnO2, Fe2O3 as activators can regulate the process of oxidation reaction, improve the properties of magnesium oxide, and significantly improve the activity of magnesium oxide.
Summary
The activity of magnesium oxide is affected by many factors, which are interrelated and ultimately determine its activity. Zehui will comprehensively consider these factors in the process of preparing highly active magnesium oxide, and then select appropriate methods and processes to achieve the desired results.
