Light-fired magnesia powder is a kind of raw material with medium basicity and chemical activity. In addition to being used as refractory and cementitious material, light-fired magnesia powder is also used in other industrial fields. In addition, the development of slag splashing technology for converter protection further expands the application scope of light burning magnesia powder. At present, the slag splashing technology mostly uses light-burned magnesia powder as pellets, such as light-burned magnesia powder pellets, carbon-containing light-burned magnesia pellets and carbon-containing calcium-containing light-burned magnesia powder pellets.
"Light burning powder" is a product of natural magnesite or brucite lightly burned at about 900 C. It is commonly known as light burning powder. Magnesium oxide is the main chemical composition of light burning powder. Magnesium oxide in general sense refers to magnesium oxide produced by chemical method. Magnesium carbonate or magnesium hydroxide is produced by chemical method using magnesium-containing raw materials, and magnesium oxide is obtained by calcination. Therefore, the so-called magnesia, in general, is the purity, particle size, and other indicators and light-burned powder have significant differences.

As magnesite is generally reduced by about 50%, the content of MgO in ores can be almost doubled by light burning. In this sense, light burning of magnesia is the most effective means of MgO enrichment. In addition, light burning is also a preparatory operation for thermal separation and some gravity separation of magnesite. Light burning of magnesia has high activity and is an ideal raw material for producing high bulk density magnesia.
Refractories generally refer to inorganic non-metallic materials with refractory degree above 1580 C, including natural ores (refractory raw materials) and various products (refractory products) processed according to a certain process flow according to certain purposes and requirements, which have certain high temperature mechanical properties and good volume stability. Refractories are important basic materials related to high temperature industry, such as iron and steel, non-ferrous metals, petrochemical, building materials, machinery, electricity, environmental protection and national defense.
Magnesium oxide (chemical formula: MgO) is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Light-burned magnesia and magnesia exist in nature in the form of periclase, which is the raw material for magnesium smelting.
Resources and Exploitation of Magnesium Raw Materials Magnesium raw materials refer to magnesium-containing minerals which can be used to produce magnesia refractories, magnesia chemical materials, metal magnesium and other products. They are mainly divided into solid minerals such as magnesite, dolomite, brucite and liquid minerals such as sea water and Salt Lake brine. Magnesite is one of the most important refractory materials in the world. It is mainly used for calcining light-burned magnesia (CCM), sintered magnesia (DBM), fused magnesia (FM) and other refractory materials. It is the basic material for producing magnesia refractories.

Magnesium oxide is widely used in daily life. Light burning powder plays a vital role in the production of some raw materials in industry. It is necessary to test the activity of magnesium oxide when purchasing magnesium oxide. For raw materials, if the activity of magnesium oxide is not enough, it will easily lead to the quality of materials not up to the standard, so its activity is very high. Important, then how to test it? Xiaobian will give you an introduction. Taking magnesium oxide for adhesive as an example, I would like to explain it to you. I hope it will be helpful to you.
Light burnt magnesium oxide contains three kinds of substances: underburned, overburned and activated magnesium oxide. 1: The so-called underfired products are part of magnesium carbonate which does not form magnesium oxide. (Controlling the setting speed of magnesite products mainly depends on the amount of underfired products;) If there are more underfired products, the burning vector will be higher, and the setting speed of magnesite products made is very fast, which will cause the bursting and deformation of magnesite products.

Information

"Light burning powder" is a product of natural magnesite or brucite lightly burned at about 900 C. It is commonly known as light burning powder. Magnesium oxide is the main chemical composition of light burning powder. Magnesium oxide in general sense refers to magnesium oxide produced by chemical method. Magnesium carbonate or magnesium hydroxide is produced by chemical method using magnesium-containing raw materials, and magnesium oxide is obtained by calcination. Therefore, the so-called magnesia, in general, is the purity, particle size, and other indicators and light-burned powder have significant differences.

Uses: Used in rubber, plastics, wires, cable dyes, paints, glass, ceramics, chemical reagents, medicine, food additives, etc. 1. Metallurgical industry: used for manufacturing refractory materials and adhesives for masonry arm, and as raw materials for manufacturing No. 2 flux and smelting magnesium metal.

2. Chemical industry: Mainly used in the production of various magnesium salts, such as magnesium oxide, magnesium hydroxide, magnesium carbonate, also used as raw materials for antifreeze.

3. Building materials: Made of hard corrosion-resistant magnesia-oxygen cement with magnesite (MgO), it can make marble, bitter earth tile, floor, ceiling, decorative board, fire-proof board, shed bracket, partition board, magnesite well cover, bathtub, doors and windows frame and movable house, etc.

4. Machinery Industry: In daily life, using magnesite can be made into mechanical packing box, triangular cushion edge and furniture, etc., which is a good material for "substituting soil for material".

5. Food industry: Bean curd made from brine (magnesium chloride aqueous solution) is more tender and delicious than that made from stone, and some food additives.

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

7. Pharmaceutical: Made of magnesium chloride "dried brine" can be used as medicine.

8. Agriculture: It can be used as magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant. Light burning powder: magnesite calcined at 750-1100 temperature is called "light burning". Its product is called light burning magnesia powder. Since magnesite burning decreases by about 50%, the content of MgO in the ore can be almost doubled by light burning. In this sense, light burning is an effective means of MgO enrichment. In addition, light burning is also a preparatory operation for magnesite thermal separation and some heavy separation. Light burning magnesia has high activity and is alive. Ideal raw material for producing high bulk density magnesia.

Light burnt magnesia mainly produces cementitious materials, such as magnesia cement, building materials for insulation and sound insulation, as well as ceramic raw materials. After chemical treatment of light burnt magnesia, a variety of magnesium salts can be made and used for medicine.
