"Lightly burned powder" is the product of light burning with natural magnesite or brucite at about 900°C. Commonly known as light burning powder. The main chemical component is magnesium oxide. Magnesium oxide in the general sense refers to magnesium oxide produced by chemical method. The price of magnesium oxide is the magnesium oxide obtained by calcining magnesium carbonate or magnesium hydroxide produced by chemical methods using magnesium-containing raw materials. Therefore, the so-called magnesium oxide is generally significantly different from the light-burning powder in terms of purity, particle size, and viability. How much is a ton of magnesium oxide


Uses: Used in rubber, plastic, wire, cable dyes, paint, glass, ceramics, chemical reagents, medicine, food additives, etc. 1. Metallurgical industry: used to manufacture refractory materials and adhesives for furnace arms, and is used for manufacturing No. 2 flux and raw material for smelting magnesium metal.

2. Chemical industry: mainly used to make various magnesium salts, such as magnesium oxide, magnesium hydroxide, magnesium carbonate, and also used as raw materials for antifreeze.


3. Building materials: made of hard and corrosion-resistant magnesia cement with magnesite (MgO), which can be used to manufacture marble, loam tiles, floors, ceilings, decorative panels, fireproof panels, greenhouse supports, partition panels, magnesite Manhole covers, bathtubs, door and window frames, and mobile homes, etc.

4. Machinery industry: In daily life, lozenge earth can be used to make mechanical packing boxes, triangular cushions and furniture, etc. It is a good material for "substituting earth for materials".


5. Food industry: Tofu made with brine (magnesium chloride aqueous solution) is more tender and delicious than stone-made tofu, and it is an additive for some foods.


6. Transportation industry: used as road ice and snow melting agent, the ice melting speed is fast, and the corrosiveness to vehicles is small, which is higher than the effect of sodium chloride. ?


7. Medicine: It can be used for medicinal purposes when it is made of magnesium chloride into "halogen".


8. Agriculture: It can be used as magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant. The price of electrical grade magnesia powder light burning powder: magnesite is calcined at a temperature of 750-1100, called "light burning", and its product is called light burning magnesium powder. Burning, the MgO content in the ore can be almost doubled. In this sense, light burning is an effective MgO enrichment method. In addition, light burning is also a preparatory work for magnesite thermal separation and some gravity separation. Light burning Magnesium has high activity and is an ideal raw material for the production of high-density magnesia.


Light-burned magnesium is mainly used to manufacture cementitious materials, such as magnesium-containing cement, building materials for thermal insulation and sound insulation, and can also be used as ceramic raw materials. After chemical treatment of light-burned magnesium, various magnesium salts can be made and used as medicine.
