Reburned magnesia is one of the most common kinds of magnesia. It is widely used in many fields. Its application mode and effect are different in different fields. So what is the use of reburning magnesia? Next, we will briefly introduce the use of refired magnesia for you.

Reburned magnesia means that when magnesite is calcined at 1800℃, carbon dioxide is completely released, magnesium oxide forms dense blocks of magnesite, weighing magnesia (also known as sintered magnesia), this reburned magnesia has a very high refractoriness. The primary component is magnesium oxide, which is made of natural super-grade magnesite through flotation purification, light burning, fine grinding, high pressure ball pressing and ultra-high temperature oil shaft kiln calcination.


Reburned magnesia is alkaline oxide, has the general properties of alkaline oxide, belongs to the cementitious material. White powder (light yellow for magnesium nitrite), odorless, tasteless, non-toxic, is a typical alkaline earth metal oxide magnesite calcined at 1800℃, carbon dioxide is completely released, magnesium oxide formed magnesite dense block, weighing burning magnesium (also known as sintered magnesia), this re-burning magnesium has a very high refractoriness. The primary component is magnesium oxide, which is made of natural super-grade magnesite through flotation purification, light burning, fine grinding, high pressure ball pressing and ultra-high temperature oil shaft kiln calcination.

Reburned magnesia mixed with magnesium chloride aqueous solution, adding a small amount of talcum powder, quartz sand, glass wire, knot forming. Refractory to 1400 degrees Celsius, up to 1700 degrees. Heavy burning magnesium, sintering degree is outstanding, chemical composition is uniform, quality is stable. Mainly used for steelmaking open - hearth, electric furnace sintering furnace bottom and ramming furnace lining.

Now, after our above brief introduction to the use of reburned magnesia, are you now have a further understanding of reburned magnesia? In fact, reburned magnesia has many uses in industrial production, and the amount of use is very large.
