What is Magnesium oxid?
Magnesium oxide, also known as MgO or magnesium oxide, is an inorganic material with a chemical composition of an ionic compound. It is a solid that is white at room temperature. Magnesium oxide is found naturally in periclase. It’s a raw material used in magnesium smelting.

Magnesium dioxide is also commonly known as magnesia, or bitter soil. Magnesium is a type of alkaline earth metal oxide. It has the same properties and characteristics as other alkaline earth metal oxides. A typical alkaline metal oxide with the chemical formula MgO is white powder (light yellow in case of magnesium nitride). It has no odor, no taste, and is non-toxic. White powder. The melting point of this material is 2852. Its boiling point is 3600. The relative density of the product is 3.58. Insoluble in alcohol and insoluble in acid or ammonium-salt solution. The solubility is 0.0062 g/100mL (0 degC).

The two main types are light magnesium oxide (LMO) and heavy magnesium dioxide (HMO). Amorphous white powder that is light and bulky. It is non-toxic, non-smelly and odorless. It has a density of 3.58g/cm3. It is only slightly soluble when mixed with pure water, organic solvents and water. The presence of carbon dioxide makes it more soluble. It can be dissolved by acid or ammonium-salt solution. After burning at high temperatures, it becomes crystals. When there is carbon dioxide present in the air, double magnesium salts are formed. The white or beige powder is a compact, heavy substance. It is easy for it to mix with water and absorb moisture as well as carbon dioxide in the air. Mixing magnesium chloride solution with the gel is very easy.
Due to the industrialization upgrade as well as the demand and growth of the high technology functional material market, several high-tech and fine products of magnesium oxide have been developed. They are mainly used in high quality lubricants and food grade.

Magnesium Oxide:

High Purity Magnesium oxide

High purity magnesium dioxide has excellent electrical insulation and alkali resistance at high temperature. The high thermal conductivity and thermal expansion coefficient have good light transmission. High temperature and heat resistant material widely used. In the ceramic field it is used to make light-transmitting ceramics crucibles or substrates. In the electrical and electrical fields for magnetic devices fillers, insulating materials fillers, and different carriers. It is used as a ceramic substratum, where it has a thermal conductivity that is two times greater than Magnesium dioxide, with tenths of the electrolyte lost. The raw material can be used for making high-purity fuses magnesia and it can also be used chemically to produce “analytical pur” magnesium dioxide.


Application field: Nanoscale magnesium oxide is characterized by a number of effects, including a surface effect, atomic size effect, and macro-tunnel effect. The agglomeration effect is eliminated after modification. It has a wide range of special functions, such as in optics and magnetism. The material has many applications and a broad range of prospects. Nano-magnesium is used widely in electronics, ceramics. oil products. coatings. In different products they have different functions. The different products they are used in have different roles.

With the growing demand for high performance flame retardant fibers in the textile sector, synthetic flame retardants offer the ideal material for the development and production of functional fabrics. In the production of refractory materials, such as sound insulation, heat isolation, refractory board, and cermets, nano-magnesium dioxide is commonly used with wood chips or shavings. Nano-magnesium Oxide is a non-toxic organic flame retardant that does not emit odors and contains a low amount of phosphorus. It is the perfect additive to develop flame-retardant fabrics. The nano-magnesium used in fuels has the ability to clean, inhibit corrosion and have a good application in coatings.

Magnesium oxide is widely used for semiconductor electronic packaging because of its excellent properties in terms of electrical, mechanical and thermal properties.
