What is Magnesium Nitride

What is Magnesium-Nitride?

Magnesium nitride is an inorganic compound that has the chemical formula Mg3N2. It is part of the cubic crystals system. At temperatures of room temperature, the pure magnesium Nitride is a greenish yellow powder but magnesium nitride with parts of magnesium oxide impurities is greyish white.

The Molar mass of magnesium oxide is 100.95g/mol. This mineral's density is 2.712g/cm3. Magnesium Nitride is completely dissolved in acid and water, but it is partially dissolved in alcohol and ether.

The melting point for magnesium nitride is 1500 degrees. Magnesium Nitride, as with many metal nitrides reacts with water to form ammonia. Often used as a catalyst. React with acid or aqueous nonmetallic oxides , forming ammonium salts and magnesium salts.

Magnesium Nitride is a kind of ceramic nature. Magnesium nitride exhibits high corrosion resistance and greatly enhances production efficiency. Magnesium is also a great material for thermal conductivity as well as high corrosion resistance and resistance to temperature. Magnesium Nitride is of additional significance because it serves as a catalyst used in the synthesizing of boron.

What is Magnesium nitride Used for?

1. Utilized as a catalyst in order to preparation of nitride compounds from other elements that have high hardness, high thermal conductivity, corrosion resistance, wear resistance, and extremely high resistance to temperature. In the first successful chemical synthesis of cubic-boron nitride the catalyst was magnesium Nitride.

2. This is a high strength steel additions to smelting. Magnesium nitride (Mg3N2) replaces the magnesium that is desulphurized during construction steel melts, which is helpful to increase the density strength, tension and bearing force of steel. In addition, the use of magnesium nitride (Mg3N2) desulfurizationcould reduce the amount of other additives, which can help lower the cost of manufacturing construction steel.

3. It is used to prepare special ceramic materials;

4. For the manufacturing of a specific alloy foaming agent;

5. Glass that is specially made to be used in the manufacturing process;

6. For catalytic crosslinking of polymers

7. For the recycling of nuclear waste;

How do I Make Magnesium Nitride?

Presently, the primary methods for making magnesium nitride include direct reaction method for magnesium powder using nitrogen, reaction method of magnesium and nitrogen in nitrogen plasma flow and the magnesium coil explosion method in nitrogen atmosphere the low pressure chemical gas technique, self-propagating high temperature synthesis process, nano-magnesium nitride synthesis methods, etc.

Recently, G. Soto et al. created amorphous magnesium Nitride films with different Mg/N ratios on Si substrates in a nitrogen molecular atmosphere using the use of pulse-laser deposition. These techniques limit their production for industrial use due to expensive costs, long processes complex operation of equipment or low yields for magnesium nutride.

The direct reaction of magnesium powder using nitrogen has an industrial use, the creation of magnesium nitride powder requires more reaction temperatures and a longer reaction time. Also, the particle's shape is not perfect and easy to disperse, that is not able to meet the requirements for industrial quality. In the case of NH3, it can be broken down into Nwhich has broken bonds quicker than N2 and the H2 that is decomposed can slow the growth of MgO, which is why ammonia gas can be used as a nitrogen source. Chen Faqin et al. used ammonia liquid as a nitrogen source to make magnesium nitride in the form of powder via direct Nitriding of magnesium powder. The following conclusions could be drawn: Using thermodynamic analysis, liquid ammonia is able to react with magnesium powder more readily than nitrogen and produce magnesium nitride. Good quality magnesium nitride with the highest purity and uniform particles can be produced at 600 degrees Celsius and in ammonia-based atmosphere for 1h, then heated to 800, ammonia flow rate of 500ml/min with the time for nitriding of 1h.
