The word activity does play a very important role for some materials. Therefore, here we will take a detailed look at the basic principles of the formation of active magnesium oxide. Activated Magnesium Oxide

1. Formation of activated magnesium oxide

During the calcination of magnesite ore in the kiln, the calcination temperature of the ore is different due to technical reasons. When the temperature reaches 400-600 degrees Celsius, its internal structure is loose, the intercrystalline pores are a little high, and the magnesia shows good activity. .

2. When the calcination temperature reaches 750-850 degrees Celsius, the porosity between crystals decreases and reaches the range of magnesium cement reaction, and the activity is moderate. When the calcination temperature is greater than 900-1000 degrees Celsius, superficial magnesium oxide is formed, and its activity is very low or even no activity. Within a certain activity range, the products with high activity are of good quality, and those with low activity are of poor quality, but this is not the case with underfired magnesium oxide. Cracking and low strength.

3. Activated magnesium oxide is magnesium oxide with hydration ability. The article comes from the Internet
