What is Magnesium oxid?
Magnesium oxide, also known as MgO or magnesium oxide, is a non-organic, ionic compound. It is a white, solid substance at room temperature. Magnesium oxide is found naturally in periclase. It’s a raw material used in magnesium smelting.

Magnesium oxid is also called magnesia or bitter soil. Magnesium is an alkaline, or amorphous oxide. It has the same properties and characteristics as other alkaline compounds. 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. Its relative density is 3,58 (25). Insoluble in alcohol and in acid solution. The solubility is 0.00062g/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, tasteless and odorless. It has a density of 3.58g/cm3. Carbon dioxide makes it more soluble than pure water in organic solvents. It can be dissolved by acid or ammonium-salt solution. It becomes crystals when heated to high temperatures. When there is carbon dioxide present in the air, double magnesium salts are formed. The white or beige powder is compact and has a large volume. 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, thermal expansion coefficient, and light transmittance are all good qualities. High temperature and heat resistant material widely used. In the ceramic field it is used to make light-transmitting ceramics, substrates etc. and in electrical materials, as magnetic device fillers, insulation material fillers, and for various 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 loss in electrolyte. The raw material can be used for making high-purity fuses magnesia and it can also be used chemically to produce “analytical purity” magnesium oxide.


Application field: Nanoscale magnesium oxide is a material with a visible small size effect. It also has measurable surface effects, quantum size effects, and macro-tunnel effect. The agglomeration effect is eliminated after modification. It has many functions in optics and other fields such as catalysis, magnetics, mechanics, chemical engineers, etc. The material has many applications and a broad range of prospects. Nano-magnesium is used widely in electronics, catalysis and ceramics. It can also be found in oil products, coatings, ceramics etc. 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 fabrics, synthetic flame-retardants offer the ideal material for the development and production of functional textiles. Nano-magnesium is commonly used with wood shavings or chips to produce refractory materials, such as light weights, heat insulations, sound insulations, and refractory fiberboards. Nano-magnesium Oxide is non-toxic, has no odor, and only a small amount of it. 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.
