What are the main characteristics of heavy burnt magnesia

Re-burned magnesia is a common kind of magnesia, and it is widely used in many fields. Many people have only heard of heavy burned magnesia, but they don't know enough about its characteristics. Today we will give you a brief introduction to the characteristics of re-burned magnesia, and hope that it will be helpful for you to choose re-burned magnesia in the future. 98 fused magnesia

The reburned magnesia is mainly made of 46.5% magnesite ore, which is calcined in a high temperature shaft kiln at about 1500℃-1800℃. The color of the product is yellow-brown. The main components of the re-burned magnesia products are magnesium oxide, calcium oxide, silicon dioxide, iron trioxide, aluminum oxide, and caustic soda. The main content of the re-burned magnesia Mgo is 80%. , 82%, 85%, 88%, 90%, 91%, 92%, 93%, the content of calcium oxide in re-burned magnesia is about 2.5%, and the content of silica in re-burned magnesia is 3.5%- 7%, the content of iron trioxide in the refired magnesia is between 0.8%-1.5%, electrical grade magnesia powder, 97 fused magnesia, 98 fused magnesia The aluminum content is about 1%, and the caustic soda content in the re-burned magnesia is less than 1%. The re-burned magnesia is mainly used in brick making and the main ideal raw material for the production of unshaped refractories. In addition, the re-burned magnesia products can also be mainly used Used in industries such as steelmaking, electric furnace bottom and ramming furnace lining.

Magnesia is also called sintered magnesia. Magnesium hydroxide is made from magnesite, brucite, or the reaction of seawater and lime milk. It is calcined at high temperature and has strong hydration ability. It is mainly used to make basic refractory materials, such as magnesia bricks and magnesia-aluminum bricks. It is used to pave steel furnace bottoms with many impurities.

Magnesia can be divided into two categories: natural magnesia and seawater magnesia or synthetic magnesia. Natural magnesia is mainly derived from natural magnesite, but due to the quality of raw ore, it is difficult to obtain high-purity and high-quality products. So far, seawater magnesia has become the main source of magnesia used in industrialized countries.
