What is Magnesium Nitride

What is Magnesium Nitride?

Magnesium nitride is an inorganic compound with the chemical formula Mg3N2. It's part of the quantum system of cubic crystals. At the temperature of room, pure magnesium Nitride is a greenish yellow powder and magnesium nitride which contains portions of magnesium oxide impurities can be grayish white.

The magnesium nitride's molar mass is 100.95g/mol. In terms of density, it is 2.712g/cm3. Magnesium Nitride is completely dissolvable in water and acid, but is partially dissolvable when mixed with alcohol and ethanol.

The melting point for magnesium nitride is 1500 degrees. Magnesium nitrideis one of the metal nitrides, reacts water and produces ammonia. It is often used as a catalyst. React with acid or aqueous nonmetallic oxidants to form ammonium salts as well as magnesium salts.

Magnesium Nitride is a ceramic substance in nature. Magnesium has excellent corrosion resistance and greatly increases production efficiency. Magnesium also has high thermal conductivity, as well with high corrosion resistance and resistance to temperature. Magnesium Nitride is of further significance since it's used as a catalyst for the creation of boron nitrogen.

What Do You Use Magnesium Nitride For?

1. Use as a catalyst to preparation of nitride compounds from other elements with high hardness and high thermal conductivity. It also provides corrosion resistance, wear resistance, and extremely high resistance to temperature. The first successful synthesizing of cubic boron this catalyst is magnesium nitride.

2. It is used for steel with high strength smelting additives. Magnesium Nitride (Mg3N2) replaces desulphurized magnesium in construction steel the smelting process, and helps in increasing the density strength that, tension and bearing capacity of steel. In addition, the use of magnesium nitride (Mg3N2) desulfurizationcould lessen the amount of additives, thus helping to reduce the cost of manufacturing construction steel.

3. Useful for preparing special ceramic materials;

4. To manufacture a special alloy foaming agent

5. For manufacturing special glass;

6. For catalytic crosslinking of polymers

7. For the recycling of radioactive waste

How to Produce Magnesium Nitride?

The current methods for making magnesium nitride are direct reactions method of magnesium powder with nitrogen, the method for resolving magnesium with nitrogen inside nitrogen plasma flow and the magnesium coil explosion method in nitrogen atmosphere Low pressure chemical gas complementary product method, self-propagating high temperature method for synthesis, nano magnesium nitride synthesis technique as well as other methods.

Recently, G. Soto et al. created amorphous magnesium Nitride films with different Mg:N ratios on Si substrates in a nitrogen-based molecular environment by in-situ pulse laser deposition. These methods hinder the production of industrial magnesium nitride due to expensive costs, long processes or complex equipment operation or a lower yield of magnesium nutride.

Although the direct reaction of magnesium powder using nitrogen has an industrial use, the creation of magnesium oxide powder requires higher reaction temperature and longer reaction time. Additionally, the particle's shape is not perfect and easy for agglomeration, and therefore, does not meet the specifications of industrial quality. N3 can be broken into Nand N2 - with broken bonds faster than N2 and the decomposed H2 is able to interfere with the formation process of MgO. Therefore, ammonia gas is an ideal nitrogen source. Chen Faqin et al. employed liquid ammonia as a nitrogen source for the preparation of magnesium nitride material by direct nitriding of magnesium powder. The following conclusions can be drawn: Through thermodynamic study, liquid ammonia might react with magnesium powder much more quickly than nitrogen for the production of magnesium nitride. Good quality magnesium nitride that is an extremely high purity and uniform particles can easily be prepared at 600 and ammonia pressure for 1 hour. Then, it's heated to 800degrees, with an ammonia flow rate of 500ml/min and the nitriding process takes 1 hour.
