What is Magnesium Nitride

What is Magnesium Nitride?

Magnesium nitride is an inorganic molecule with the chemical formula Mg3N2. It's part a Cubic Crystal System. At low temperatures, pure magnesium Nitride is a greenish yellow powder however, magnesium nitride that contains the magnesium oxide particles is grayish white.

The Molar mass of magnesium nutride is 100.95g/mol. Their density stands at 2.712g/cm3. Magnesium Nitride is completely dissolved in acid and water, but is partially dissolvable when mixed with the ethanol and ether.

The melting point of magnesium nitride can be found at 1500 degrees. Magnesium nitrideis one of the metal nitrides water to form ammonia. It is frequently used as a catalyst. They react with acid or nonmetallic oxides in order to produce ammonium salts and magnesium salts.

Magnesium Nitride is a form of ceramic in nature. Magnesium-nitride has superior corrosion resistance, and significantly improves productivity. Magnesium also has high thermal conductivity, as well in high corrosion resistance and resistance to temperature. Magnesium is also of great importance due to its usage as a catalyst for the production of boron-Ni.

What Is Magnesium-Nitride Used For?

1. Use as a catalyst to make the nitride out of other elements with high hardness with high thermal conductivity wear resistance, corrosion resistance, and resistant to high temperatures. In the first successful creation of cubic boron nitride, an active catalyst came from magnesium nitride.

2. A high-strength steel additions to smelting. Magnesium Nitride (Mg3N2) is a substitute for desulphurized magnesium during construction steel smelting. It is useful to improve the density, strength as well as the bearing force of steel. In addition, the use of magnesium Nitride (Mg3N2) desulfurizationcould reduce the amount of other additives, thus helping to decrease the cost of production of construction steel.

3. The use of ceramic is to prepare specific materials;

4. To make a special alloy foaming agent

5. Special glass for manufacturing;

6. For catalytic polymer crosslinking;

7. For the recycling of nuclear waste;

How to Make Magnesium Nitride?

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

Recently, G. Soto et al. created amorphous magnesium nitride film with different ratios of Mg:N on Si substrates in a nitrogen-based molecular environment through in-situ pulse laser deposition. These techniques restrict their industrial production because of high cost, long process and complex operation of equipment or a lower yield of magnesium Nitride.

Although the direct reaction between magnesium powder and nitrogen can have significant industrial potential, the making of magnesium nitride-based powder requires higher temperature for the reaction and a long reaction times, and the form of the particles isn't perfect and easy to aggregate, and therefore, does not meet the specifications of industrial quality. It is possible to decompose NH3 into Nthat has broken bonds faster than N2 and decomposed H2 may hinder the formation of MgO. Therefore, ammonia gas can be used as the nitrogen source. Chen Faqin et al. Utilizing liquid ammonia as the nitrogen source to make magnesium nitride powder through direct Nitriding of magnesium powder. The following conclusions could be drawn: By thermodynamic analyses, liquid ammonia could react to magnesium powder more efficiently than nitrogen to produce magnesium nitride. The best quality magnesium nitride powder with high purity and uniform powder particles is made by heating it to 600 and ammonia atmosphere for 1hand then heated to 800, ammonia flow rate of 500ml/min with one hour of nitriding.
