What is Magnesium Nitride

What is Magnesium Nitride?

Magnesium nitride is an inorganic compound that has the chemical formula Mg3N2. It's part of the cubic crystal system. At normal temperature, pure nutridide is yellow-green However, magnesium nitride that has an element of magnesium oxide impurities is grayish white.

The molar mass of magnesium nitride is 100.95g/mol. Its density 2.712g/cm3. Magnesium nitride is completely dissolved in water and acid but is partially dissolvable when mixed with Ether and ethanol.

The melting point for magnesium nitride is 1500 °. Magnesium nitrideis one of the metal nitrides, reacts with water to make ammonia. It is commonly used as a catalyst. React with acid , or aqueous nonmetallic oxides in order to produce ammonium salts as well as magnesium salts.

Magnesium nitride is ceramic in nature. Magnesium is abrasion-resistant material that has excellent resistance, which greatly increases productivity. Magnesium Nitride also has high thermal conductivity, aswell in high corrosion resistance and temperature resistance. Magnesium Nitride has an additional significance due to its use as a catalyst for synthesizing of boron.

What Is Magnesium-Nitride Used For?

1. Utilized as a catalyst in order to making nitride from other elements with high hardness along with high thermal conductivity corrosion resistance, wear resistance, and higher temperature resistance. In the first successful creation of cubic boron nitride this catalyst is magnesium Nitride.

2. It is used for steel with high strength and smelting additives. Magnesium nitride (Mg3N2) is a substitute for the magnesium that is desulphurized during construction steel smelting. It is useful to increase the density strength of the steel, as well as the tension and bearing force of steel. In addition, the process of magnesium Nitride (Mg3N2) desulfurizationmay reduce the use of other additives, thereby helping to reduce the production cost of construction steel;

3. Useful for preparing special ceramic materials;

4. For the manufacture of special alloy foaming agent;

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

6. To crosslink catalytically-linked polymers.

7. To recycle nuclear waste

How do I Make Magnesium Nitride?

The main preparation methods of magnesium nitride are direct reactions method for magnesium powder using nitrogen, method of reaction of magnesium and nitrogen in nitrogen plasma flow as well as the method for the explosion of magnesium coils in nitrogen atmosphere, low pressure chemical gas complementary product method, self-propagating high temperature process for synthesis, nano magnesium Nitride synthesis method and more.

Recently, G. Soto et al. produced amorphous magnesium-nitride films with different Mg:N ratios Si substrates in a molecular nitrous environment through the use of pulse-laser deposition. This method limits their industrial production because of high cost, long process as well as the complexity of operating equipment or a low yield of magnesium nutride.

While the direct reaction of magnesium powder with nitrogen is of commercial value, the manufacture of magnesium nitride-based powder requires more reaction temperatures and a longer reaction times, and the form of the particles isn't perfect as well as easy to agglomerate which doesn't meet needs of industrial grade. In the process of decomposition, NH3 can form Nthat has broken bonds more easily than N2, and the decomposed H2 will slow the growth of MgO, which is why ammonia gas is a suitable nitrogen source. Chen Faqin et al. utilized liquid ammonia for nitrogen source to prepare magnesium nitride using direct nitriding of magnesium powder. The following conclusions can be drawn: From a thermodynamic analysis, liquid amonia could react with magnesium powder much more quickly than nitrogen to produce magnesium nitride. Good quality magnesium nitride powder that has high purity and uniform powder particles is made by heating it to 600 and ammonia in 1 hour. It is then heated up to 800, ammonia flow rate of 500ml/min and one hour of nitriding.
