Magnesite is magnesium oxide, which can be made from magnesite, brucite, dolomite, serpentine, olivine and other minerals. Generally, magnesite and brucite can be used as raw materials to calcine and decompose into magnesium oxide, which crystallizes differently due to different calcination temperatures. The magnesium oxide calcined at 600-1000 ℃ is called active magnesium oxide, and the magnesium oxide calcined at 1400-1800 ℃ is called dead burned magnesium oxide. The above two kinds of magnesium oxide are also commonly called light magnesium oxide, commonly known as furnace magnesia.

The fused magnesite is formed by melting magnesite in electric arc furnace and cooling it. Magnesite is one of the important raw materials for refractories. It is used to manufacture various magnesia bricks, magnesia alumina bricks, magnesia carbon bricks, ramming materials, furnace repairing materials, etc. Those with more impurities are used to pave the bottom of the steelmaking furnace. Magnesia can be divided into fused magnesia, medium grade magnesia, high-purity magnesia and calcined magnesia.

According to the analysis, from the perspective of supply and demand, the current factory stock is generally tight. In addition, the arrival of the summer solstice on June 21 means that the "mode" is open throughout the year, workers work hard, and the factory output is limited. It is expected that the magnesium factory quotation will remain firm and upward, and the magnesium price will be difficult to decline. Considering that it is difficult for downstream users to accept the high price, and that downstream enterprises will also carry out equipment maintenance in summer, it is not easy for magnesium prices to rise due to weak demand, so magnesium market will be more stable this week.

The calcined magnesite is mainly composed of magnesite ore with a content of more than 46%. When the magnesite ore is calcined and heated in a high temperature shaft kiln to 1400-1800 ℃, Mg (CO3) is completely decomposed to generate periclase, which becomes hard reddish brown calcined magnesium with high fire resistance. It is an ideal raw material for producing unshaped refractory materials. The products are used for steel making open hearth furnace, electric furnace bottom and ramming furnace lining.

Magnesite is calcined at high temperature from magnesite, bischofite or magnesium hydroxide extracted from seawater. It is a general term for the products of magnesite and other magnesia raw materials that have been treated at high temperature to reach the sintering process. Magnesite produced by burning natural magnesite with one-step or two-step burning process using high-temperature equipment such as shaft kiln and rotary kiln is called sintered magnesite; Seawater magnesia is produced by extracting magnesium oxide from seawater after magnesite and other raw materials are melted in an electric arc furnace and cooled.
