Light Burnt Magnesium Powder Introduces the Properties of Its Magnesium Oxide

Physical properties: white light powder, odorless, tasteless, insoluble in water and ethanol, melting point 2852 ℃, boiling point 3600 ℃, light burnt magnesium powder magnesium oxide (light burnt powder) has high refractory insulation properties. It can be transformed into crystal after high temperature burning above 1000℃, and it will become dead-burned magnesia (light burning powder) or sintered magnesia (light burning powder) when it rises above 1500℃. The detection of specific surface area is actually a time-consuming task. Due to the difference in the adsorption capacity of the samples, the test of some samples may take a whole day. If the test process is not fully automated, the tester cannot leave at all times, and must A high degree of concentration, observing the instrument panel, and manipulating the knobs, will lead to the failure of the test process, which will waste a lot of precious time of the testers. Light Burnt Magnesium Powder

Chemical properties: Magnesium oxide (light-burned magnesium powder) is an alkaline oxide with the general properties of alkaline oxides

When exposed to the air, it is easy to absorb water and carbon dioxide and gradually become basic magnesium carbonate. The light product is faster than the heavy product. It combines with water to form magnesium hydroxide (light calcined powder), which is slightly alkaline reaction, saturated aqueous solution The pH is 10.3. Soluble in acid and ammonium salts, insoluble in water, and its solution is alkaline. Insoluble in ethanol.

MgO+2HCl→MgCl2+H2O

MgO+NH4Cl→MgCl2+NH3↑+2H2O

It acts slowly with water to form magnesium hydroxide (light-burned magnesium powder has strong refraction in the visible and near-ultraviolet light range.

Classification: divided into light magnesium oxide (light burning powder) and heavy magnesium oxide (light burning powder). The light volume is fluffy as a white amorphous powder. Odorless, tasteless and non-toxic. Density 3.58g/cm3. Insoluble in pure water and organic solvents, the solubility in water increases due to the presence of carbon dioxide. Soluble in acid and ammonium salt solution. After high temperature burning into crystals. In case of carbon dioxide in the air, magnesium carbonate double salt is formed. Heavy volume is compact, white or beige powder. It is easy to combine with water, and it is easy to absorb moisture and carbon dioxide when exposed to the air. It is easy to gel and harden when mixed with magnesium chloride solution.

Field of application: Determination of sulfur and pyrite in coal and sulfur and arsenic in steel. Used as a standard for white pigments. Light magnesia (light fired powder) is mainly used as a raw material for the preparation of ceramics, enamels, refractory crucibles and refractory bricks. Also used as polisher binder url] paint] and filler for paper, accelerator and activator for neoprene and fluororubber. After being mixed with solutions such as magnesium chloride, it can be made into magnesium oxide (light-burned powder) water. In medicine, it is used as an antacid and a laxative for gastric hyperacidity and duodenal ulcer disease. In the chemical industry, it is used as a catalyst and a raw material for the manufacture of magnesium salts. It is also used in the manufacture of glass, dyed meal, phenolic plastics, etc. Heavy Magnesium Oxide (Light Burnt Powder) is used in the rice milling industry for firing mills and semi-drums. The construction industry is used to make artificial chemical floors, artificial marble, heat protection panels, sound insulation panels, and plastic industry as fillers. It can also be used to produce other magnesium salts.
