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 make magnesium nitride, magnesium bars can be burned in nitrogen. Often used as a catalyst.

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. 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 aqueous non-metallic oxides to form ammonium and magnesium salts.

Preparation of Magnesium Nitride

To make magnesium nitride, magnesium bars can be burned in nitrogen. The reaction equation is:

In the above reaction, if the nitrogen gas is impure, it is easy to produce a product containing magnesium oxide. The method of reaction in dry NH3 gas is better.

Put the magnesium chips 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 to the T-shaped tube. The end of the porcelain tube is connected with a U-shaped tube, which is filled with desiccant, half of which are CaO sheets and the other half are KOH sheets. 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 suction back, 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 bubbles, indicating that the air in the porcelain tube has been swept out. The temperature was raised to 800-850°C, and the magnesium powder was heated for 4 hours. The magnesium powder becomes hot, marking the start of the reaction, and at the same time hydrogen must be produced. During the reaction, the pressure of NH3 should be higher than the outside atmospheric pressure to avoid back suction. After the reaction, 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 highly deliquescent and must be stored in dry containers.

If the magnesium ribbon burns in air, in addition to magnesium oxide, some magnesium nitride will be produced.

Application of magnesium nitride Mg3N2

Application field of high-purity magnesium oxide Mg3N2: Field: High-purity magnesium oxide has excellent alkali resistance and electrical insulation at high temperature. High thermal expansion coefficient and thermal conductivity, with good light transmittance. Widely used as high temperature and heat resistant materials. In the field of ceramics, it is used as raw materials for transparent ceramic crucibles and substrates in the fields of electrical materials and electric fields, as fillers for magnetic devices, fillers for insulating materials, and various carriers. Ceramic substrate, the thermal conductivity is more than 2 times 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 fused magnesium oxide, which can be chemically used as "analytical pure" magnesium oxide.

Application fields of nano-magnesium oxide Mg3N2: N-type magnesium oxide has obvious small size effect, surface effect, quantum size effect and macroscopic tunnel effect. It has important application value and broad prospects in the fields of function, mechanics, chemical industry, etc., 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. For different products, play different roles. Used as flame retardant in chemical fiber and plastic industries; used as high-temperature dehydrating agent in the production of silicon steel sheets, advanced ceramic materials, electronic industry materials, etc.; used as adhesives and additives in industry. Chemical raw materials; high-frequency magnetic rod antennas in the radio industry, fillers for magnetic equipment, fillers for insulating materials and various carriers; refractory fibers and refractory materials, magnesia-chrome bricks, heat-resistant paint fillers, high-temperature insulating instruments, electrical, cables , optical materials and steelmaking; electrical insulating materials, manufacture of crucibles, furnaces, insulating pipes (tubular elements),

In the textile field, with the increasing demand for high-performance flame-retardant fibers, synthetic new high-performance flame retardants provide ideal materials for the development of functional fabrics. Nano-magnesium oxide is often used with wood chips and shavings to make refractory materials such as lightweight, sound and thermal insulation, refractory fiberboard and cermet. Compared with some traditional phosphorus- or halogen-containing organic flame retardants, nano-magnesium oxide is non-toxic, odorless and less added, and is an ideal additive for developing flame retardant fibers. In addition, nano-magnesium oxide used for fuel has strong cleaning and corrosion inhibition ability, 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.
