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

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.

Physical property

White or light yellow powder, odorless, tasteless, insoluble in water and ethanol, melting point 2852 C, boiling point 3600 C, magnesium oxide has a high refractory insulation performance. It can be transformed into crystals by high temperature burning above 1000 C and sintered magnesia or sintered magnesia when it rises above 1500 C

Chemical Properties: Magnesium oxide is an alkaline oxide with the general properties of alkaline oxide.

Exposed to air, it is easy to absorb water and carbon dioxide and gradually become basic magnesium carbonate. Light products are faster than heavy products. Water combines to form magnesium hydroxide, which is slightly alkaline. The pH of saturated water solution is 10.3. Soluble in acid and ammonium salt, insoluble in water, its solution is alkaline. It is insoluble in ethanol.

The ionic equation is MgO+2H+=Mg2++H2O.

MgO+2NH4+=Mg2++2NH3+H2O

Slow interaction with water to form magnesium hydroxide

It has strong refractivity in the visible and near-ultraviolet light range.

Classification: Light magnesium oxide and heavy magnesium oxide. Light bulk, white amorphous powder. It is odorless, tasteless and non-toxic. The density was 3.58g/cm3. It is insoluble in pure water and organic solvents, and its solubility in water increases with the presence of carbon dioxide. It can dissolve in acid and ammonium salt solution. It is transformed into crystals by high temperature burning. When exposed to carbon dioxide in the air, magnesium carbonate compound is formed. Heavy matter is compact in volume.

White or beige powder. It is easy to combine with water and absorb water and carbon dioxide in exposed air. It is easy to gel and harden when mixed with magnesium chloride solution.
