What is Magnesium Nitride

What is Magnesium Nitride?

Magnesium nitride, is an inorganic compound with the chemical formula Mg3N2. It's part the cubic crystal system. At the temperature of room, pure magnesium nutride is a color of yellow and green However, magnesium nitride that has portions of magnesium oxide impurities appears grayish white.

The Molar mass of magnesium Nitride is 100.95g/mol. The density of the mineral is 2.712g/cm3. Magnesium Nitride is totally dissolved in acid and water, but is dissolvable in Ether and ethanol.

The melting point for magnesium is 1500 degrees. Magnesium, like other metal nitrides water to create ammonia. Sometimes, it is used as catalyst. React with acid or aqueous nonmetallic oxides to form ammonium salts and magnesium salts.

Magnesium Nitride is a ceramic substance in nature. Magnesium nitride has high corrosion resistance and dramatically improves productivity. Magnesium nitride has also high thermal conductivity as well with high corrosion resistance and resistance to temperature. Magnesium nitride has another great significance as it's used as a catalyst creation of boron nitrogen.

What is Magnesium Nitride used for?

1. This is used as a catalyst creating the nitride elements with high hardness along with high thermal conductivity corrosion resistance, wear resistance and very high-temperature resistance. The first successful synthesis of cubic boron nitride it was the catalyst that was used, magnesium Nitride.

2. Useful for high strength steel additions to smelting. Magnesium Nitride (Mg3N2) is a substitute for the magnesium that has been desulphurized for construction in smelting. This helps in increasing the density strength, tension and bearing force of steel. In addition, using of magnesium Nitride (Mg3N2) desulfurizationcould reduce the quantity of other ingredients, and thus help to decrease the cost of production of construction steel;

3. It is used to prepare special ceramic materials;

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

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

6. For crosslinking catalytically produced polymers

7. To reuse nuclear waste;

How do I Make Magnesium Nitride?

The main preparation methods of magnesium nitride consist of direct reaction method for magnesium powder using nitrogen, the reaction method of magnesium and nitrogen in nitrogen plasma flow using a magnesium coil blast method in nitrogen atmosphere as well as low-pressure chemical gas complementary product method, self-propagating high temperature synthesis process, nano magnesium nitride synthesizer for example.

Recently, G. Soto et al. created amorphous magnesium nitride film with different Mg:N ratios on Si substrates in a nitrogen-based molecular environment using in-situ pulse laser deposition. These techniques limit their industrial application due to their high costs, the lengthy process complicated equipment operation or low yields of magnesium oxide.

Although the direct reaction of magnesium powder with nitrogen holds industrial benefits, the process of magnesium powder requires greater reaction temperatures and a longer reaction time. Additionally, the shape of particles is incomplete and easy to form agglomerates, which does not meet demands of industrial quality. The decomposition of NH3 may be accomplished into Nwith broken bonds quicker than N2 and the decomposed H2 could stop the formation of MgO. This is why ammonia can be used as a nitrogen source. Chen Faqin et al. employed liquid ammonia as a nitrogen source to make magnesium nitride powder by direct the nitriding process of magnesium powder. The following conclusions could be drawn: By thermodynamic analysis, liquid ammonia can react with magnesium powder more easily than nitrogen for the production of magnesium nitride. magnesium nitride powder with the highest purity and uniform particles is made by heating it to 600 and ammonia pressure for 1h, after which it is heated to 800°C, with an ammonia flow rate of 500ml/min and the nitriding period of 1 hour.
