What is Magnesium Nitride?

Magnesium Nitride is an inorganic compound having the chemical formula Mg3N2. It belongs to the Cubic Crystal System. At the temperature of room, pure magnesium nutridide is a bright yellow-green color, but magnesium nitride containing part of magnesium oxide impurities appears grayish white.

The Molar mass of magnesium-nitride is 100.95g/mol. In terms of density, it is 2.712g/cm3. Magnesium Nitride is completely dissolved in water and acid, however, it is partially dissolvable in the ether and ethanol.

The melting point of magnesium nitride reaches 1500 degrees. Magnesium nitrideis one of the metal nitrides water to form ammonia. Often used as a catalyst. React with acidic or aqueous nonmetallic oxidants to form ammonium salts and magnesium salts.

Magnesium nitride , a type of ceramic, is found in nature. Magnesium Nitride has a high corrosion resistance, and significantly improves production efficiency. Magnesium nitride has also high thermal conductivity, as well being resistant to corrosion and temperature resistance. Magnesium Nitride is of further significance because it serves as a catalyst in the creation of boron nitrogen.

What is Magnesium Nitride Used For?

1. A catalyst used to preparation of nitride compounds from other elements with high hardness and thermal conductivity. It is also a good choice for corrosion resistance, wear resistance, and high temperature resistance. The first successful formula for cubic boron it was the catalyst that was used, magnesium Nitride.

2. Utilized for high-strength steel additions to smelting. Magnesium Nitride (Mg3N2) replaces the magnesium that is desulphurized during construction steel smelting, which is beneficial to increase the density, strength tension, and bearing strength of steel. In addition, using of magnesium nitride (Mg3N2) desulfurization, may lessen the amount of ingredients, and thus help to lower the cost of production for construction steel;

3. This is used to make special ceramic materials;

4. For the production of a special alloy foaming agent

5. Special glass is made for the purpose of manufacturing;

6. To crosslink catalytically-linked polymers.

7. To reuse radioactive waste

How do I Make Magnesium Nitride?

Presently, the primary methods for making magnesium nitride are direct reactions method for magnesium powder using nitrogen, reaction method of magnesium with nitrogen inside nitrogen plasma flow as well as the method for the explosion of magnesium coils in nitrogen atmosphere and low pressure chemical gas supplementing method for product, self-propagating high temperature synthesis process, nano magnesium nitride method of synthesis, and so on.

Recently, G. Soto et al. made amorphous magnesium oxide films with different Mg:N ratios on Si substrates in a nitrogen-based molecular environment through an application of pulsed lasers. These techniques restrict the production of industrial magnesium nitride due to the high price, lengthy process, complex equipment operation, or a low yield of magnesium nitride.

Although the direct reaction of magnesium powder in nitrogen has economic value, the production of magnesium nitride-based powder requires greater reaction temperatures and a longer reaction time, and the shape of particles is incomplete as well as easy to agglomerate which isn't able to meet demands of industrial-grade quality. In the case of NH3, it can be broken down into Nwith broken bonds more easily than N2, and H2 decomposed may hinder the formation of MgO. This is why ammonia can be used as the nitrogen source. Chen Faqin et al. utilized liquid ammonia for nitrogen source for the preparation of magnesium nitride in the form of powder via direct nutriding of magnesium. The following conclusions can be drawn: Based on thermodynamic analysis, liquid amonia could react with magnesium powder more readily than nitrogen in the preparation of magnesium nitride. magnesium nitride that is good purity and uniform particles can easily be prepared at 600 and ammonia in 1 hour. It is then heated up to 800degrees, with an ammonia flow rate of 500ml/min , and an nitriding duration of 1h.
