Preparation of magnesium nitride?

What is magnesium nitride?

Magnesium nitride is an inorganic compound composed of nitrogen and magnesium, with a molecular formula of Mg3N2 and a molecular weight of 100.9494. Belongs to the cubic crystal system. Pure magnesium nitride is yellow-green powder at room temperature, but magnesium nitride containing some magnesium oxide impurities is off-white. Like many metal nitrides, magnesium nitride reacts with water to form ammonia. To prepare magnesium nitride, the magnesium bar can be burned in nitrogen. Often used as a catalyst.

The physical and chemical properties of magnesium nitride

Magnesium nitride (Mg3N2) is an inorganic compound of cubic crystal system composed of nitrogen and magnesium. Pure magnesium nitride is yellow-green powder at room temperature, but magnesium nitride containing some magnesium oxide impurities is off-white. Easily soluble in acid, slightly soluble in ethanol and ether.

Like many metal nitrides, magnesium nitride reacts with water to form ammonia. Reacts with acids or water-containing non-metal oxides to generate ammonium and magnesium salts.

Preparation of magnesium nitride

To prepare magnesium nitride, the magnesium bar can be burned in nitrogen. The reaction equation is:

In the above reaction, if the nitrogen is not pure, it is easy to produce products containing magnesium oxide. The method of reaction in dry NH3 gas is better.

Put the magnesium flakes into a porcelain boat or a sintered magnesium boat. The boat is installed in a porcelain tube. One end of the porcelain tube is connected with a T-shaped tube. The end of the porcelain tube is connected with a U-shaped tube, and the tube is filled with desiccant, half of which are CaO fragments and the other half are KOH fragments. The gas discharged from the reaction tube is absorbed by the absorption device, which is two conical flasks filled with dilute sulfuric acid. To prevent back suction, do not insert the tube of the first absorption bottle below the surface of the dilute sulfuric acid.

Pour dry NH3 and N2 into the porcelain tube until the second absorption bottle no longer bubbling, indicating that the air in the porcelain tube has been purged. The temperature is increased to 800-850°C, and the magnesium powder is heated for 4 hours. The magnesium powder becomes hot, marking the beginning of the reaction, and H2 must be produced at the same time. During the reaction, the pressure of NH3 should be greater than the outside atmospheric pressure to avoid back suction. After the reaction is over, turn off NH3, keep the original temperature, and continue to pass N2 for 1.5h to remove NH3·Mg3N2 adsorbed on Mg3N2. NH3·Mg3N2 is very deliquescent and must be stored in a dry container.

If the magnesium belt is burned in the air, in addition to magnesium oxide, some magnesium nitride will be produced.

Application of magnesium nitride Mg3N2

High-purity magnesium oxide Mg3N2 application areas: Fields: High-purity magnesium oxide has excellent alkali resistance and electrical insulation at high temperatures, high thermal expansion coefficient, high thermal conductivity, and good light transmittance. It is widely used as high temperature and heat resistance materials . In the field of ceramics, it is used as a raw material for transparent ceramic crucibles and substrates in the field of electrical materials and electric fields, as a filler for magnetic devices, as a filler for insulating materials, and various carriers. The thermal conductivity of the ceramic substrate is more than twice that of magnesium oxide, and the loss of electrolyte is only 1/10 of that of magnesium oxide. It can also be used as a raw material for high-purity molten magnesium oxide, and can be chemically used as "analytical pure" magnesium oxide.

Application field of oxide nano-magnesium Mg3N2: N-oxide anus-magnesium has obvious small size effect, surface effect, quantum size effect and macro tunnel effect.After the modification, there is no agglomeration.It has many special optical functions, catalysis , Magnetism, mechanics, chemical engineering, etc. It has important application value and broad prospects, and is an important new material in the 21st century. Nano-magnesium oxide is widely used in electronics, catalysis, ceramics, petroleum products, coatings and other fields. Used in different products to play different roles. It is used as a flame retardant in the chemical fiber and plastic industries; it is used as a high-temperature dehydrating agent in the production of silicon steel plates, advanced ceramic materials, and electronic industry materials, and as a binder and additive in the industry. Chemical raw materials; radio industry high-frequency magnetic rod antennas, magnetic equipment fillers, insulating material fillers and various carriers; refractory fibers and refractory materials, magnesia chrome bricks, heat-resistant coating fillers, high-temperature insulation meters, power, cables, optical materials and smelting Steel; electrical insulating materials, manufacturing crucibles, electric furnaces, insulated pipes (tubular elements),

In the textile field, as the demand for high-performance flame-retardant fibers continues to increase, synthetic new high-performance flame retardants provide ideal materials for the development of functional fabrics. Nano-magnesium oxide is usually used in conjunction with wood chips and shavings to make refractory materials such as light weight, sound insulation, heat insulation, refractory fiberboard, and cermet. Compared with some traditional phosphorus-containing or halogen-containing organic flame retardants, nano-magnesium oxide is non-toxic, odorless, and has a small addition amount. It is an ideal additive for the development of flame-retardant fibers. In addition, nano-magnesium oxide used for fuel has strong cleaning and corrosion inhibition capabilities, and has good application prospects in coatings.

Magnesium oxide is widely used in the field of semiconductor electronic packaging due to its excellent electrical, thermal and mechanical properties.
