What is light burned magnesia? You know what?

Magnesium oxide used in the production of magnesium oxychloride cement is correctly called light burning magnesium oxide, commonly known as light burning powder, which is made of magnesite after calcination at 700-800 degree high temperature, so it is called light burning magnesium oxide.

Magnesium oxide with large crystal clearance and considerable surface energy is produced during calcination of magnesite. After mixing with the brine mixed with magnesium chloride, the active magnesium oxide has a large specific surface area and is easy to absorb magnesium chloride molecules, thus forming 518 crystal phase. The activity of magnesium oxide reacts with the brine modulated by magnesium chloride.

The reactive magnesium oxide is formed by the reaction of the light burning powder with water vapor.

The color of magnesium oxide mainly depends on the color of ore, the content of silicon oxide and caustic soda in magnesium oxide.

There is nothing to say about ore, different place ore color is different, basically cannot change.

The light burning powder with severe dampness in production cannot be used. The lighter powder can be sifted to reduce the dosage of brine appropriately.

The silicon oxide in magnesium oxide belongs to impurities in magnesium oxide. The higher the silicon oxide, the whiter the color. The main component of talc powder is silicon oxide, so the color is particularly white. However, the strength and solidification time of silicon-oxide products exceeding 8% are affected.

The content of magnesium oxide in 85 light calcined magnesium powder is only between 83-84, and that in 90 light calcined magnesium powder is about 88. Due to the great pressure of environmental protection, its production is not stable, and its output is difficult to be guaranteed.

Metallurgical, refractory and building materials industries need a large number of light burning powder, heavy burning powder, electrofused magnesium oxide; Rubber, ceramics and other industries need industrial magnesium oxide, which belongs to the bulk of traditional products.
