What is Magnesium Nitride?

Magnesium Nitride is an inorganic molecule with the chemical formula Mg3N2. It's part a cubic crystal system. At room temperature, pure magnesium Nitride is a greenish yellow powder However, magnesium nitride that has an element of magnesium oxide impurities is greyish white.

The Molar mass of magnesium nitride is 100.95g/mol. Its density 2.712g/cm3. Magnesium nitride is completely dissolved in acid and water, but is dissolvable in both ethanol and ether.

The melting point for magnesium nitride is 1500 °. Magnesium nitrideis one of the metal nitrides, reacts with water and produces ammonia. A catalyst is often employed. React with acid or nonmetallic oxides to create ammonium salts as well as magnesium salts.

Magnesium Nitride is a kind of ceramic nature. Magnesium nitride is highly resistant to corrosion resistance, which greatly increases production efficiency. Magnesium is also a great material for thermal conductivity as well being highly resistant to corrosion as well as resistance to temperature. Magnesium is also of great importance as it's utilized as a catalyst in the formation of boron.

What is Magnesium Nitride used for?

1. As a catalyst, it is used to you are preparing the nitride of other elements with high hardness with high thermal conductivity wear resistance, corrosion resistance and extreme temperature resistance. In the first successful synthesizing of cubic boron, it was the catalyst that was used, magnesium nitride.

2. Utilized for high-strength steel melting additives. Magnesium Nitride (Mg3N2) is a substitute for the magnesium that has been desulphurized for construction in smelting. This helps in increasing the density strength of the steel, as well as the tension and bearing force of steel. In addition, the application of magnesium Nitride (Mg3N2) desulfurization can reduce the amount of additives, thus helping to decrease the cost of production of construction steel;

3. Used to prepare special ceramic materials;

4. In the process of making a special alloy foaming agent;

5. In the manufacture of special glass

6. Crosslinking of catalytic polymers;

7. To recycle nuclear waste

How Do You Produce Magnesium Nitride?

The main methods for making magnesium nitride are direct reaction method of magnesium powder with nitrogen, reaction method of magnesium and nitrogen in nitrogen plasma flow methods for magnesium coils in nitrogen atmosphere low pressure chemical gas complementary product method, self-propagating high temperature synthesis process, nano magnesium nitride synthesizer, and so on.

Recently, G. Soto et al. produced amorphous magnesium-nitride films featuring different Mg:N ratios Si substrates in a molecular nitrogen environment through Pulse laser deposition. These methods limit their industrial production due to the cost of production, lengthy process and complex operation of equipment or the poor yield of magnesium nutride.

The direct reaction of magnesium powder with nitrogen is of industrial value, the production of magnesium nitride requires more reaction temperatures and a longer reaction time, and the shape of the powder is insufficient as well as easy to agglomerate which can not meet the requirements of industrial quality. The NH3 is decomposed into Nthat has broken bonds much more quickly than N2 and the H2 that is decomposed can stop the formation of MgO, so ammonia gas is a suitable nitrogen source. Chen Faqin et al. utilized liquid ammonia as a nitrogen source for the preparation of magnesium nitride via direct the nitriding process of magnesium powder. The following conclusions can be drawn from thermodynamic analysis, liquid ammonia is able to react with magnesium powder faster than nitrogen and produce magnesium nitride. Good quality magnesium nitride powder with good purity and uniform particles can be made by heating them to 600 and ammonia pressure for 1h, after which it is heated to 800degrees, with an ammonia flow rate of about 500ml/min and an nitriding duration of 1h.
