What is Magnesium-Nitride?
Magnesium nitride, is an inorganic compound having the chemical formula Mg3N2. It’s part of the cubic crystal system. At temperatures at room temperature, pure magnesium Nitride is a greenish yellow powder However, magnesium nitride that has a portion of magnesium oxide impurities is greyish white.
The Molar mass of magnesium oxide is 100.95g/mol. Density is 2.712g/cm3. Magnesium Nitride is completely dissolvable in water and acid but is only partially dissolved in ether and ethanol.
The melting temperature of magnesium nitride lies at 1500 degrees. Magnesium nitride, like many metal nitrides water to produce ammonia. Often used as a catalyst. React with acid or nonmetallic oxides that result in ammonium salts and magnesium salts.
Magnesium nitride , a type of ceramic, is found in nature. Magnesium has excellent corrosion resistance, and significantly improves production efficiency. Magnesium nitride also boasts high thermal conductivity, aswell as high corrosion resistance and resistance to temperature. Magnesium nitride also has a great significance since it’s used as a catalyst in the chemical synthesis of boron.
What is Magnesium nitride Used for?
1. Utilized as a catalyst in order to make the nitride out of other elements with high hardness as well as high thermal conductivity. corrosion resistance, wear resistance and extremely high resistance to temperature. The first successful production of cubic boron-nitride, it was the catalyst that was used, magnesium nitride.
2. Utilized for high-strength steel Smelting additives. Magnesium nitride (Mg3N2) replaces desulphurized magnesium in construction Smelting, which can help in increasing the density strength in tension and bearing power of steel. In addition, using of magnesium Nitride (Mg3N2) desulfurization can reduce the amount of components, thereby helping lower the cost of production for construction steel;
3. For the preparation of special ceramic materials;
4. To make a special alloy foaming agent;
5. Special glass for manufacturing;
6. For catalytic crosslinking of polymers
7. To reuse nuclear waste;
How do I Make Magnesium Nitride?
At present, the main preparation methods of magnesium nitride involve direct reaction method for magnesium powder using nitrogen, reaction method of magnesium with nitrogen inside nitrogen plasma flow, magnesium coil explosion method in nitrogen atmosphere low pressure chemical gas process, self-propagating high temperature synthesis method nano magnesium nitride synthesis method, and so on.
Recently, G. Soto et al. produced amorphous magnesium-nitride films with different Mg:N ratios on Si substrates in a molecular nitrogen-filled environment using the use of pulse-laser deposition. These methods are limited in their industrial production due to costly costs, long processing complex operation of equipment or a lower yield of magnesium Nitride.
While the direct reaction of magnesium powder with nitrogen has industrial benefits, the process of magnesium oxide powder requires higher temperatures for reaction and a longer reaction time. Additionally, the shape of the powder is insufficient as well as easy to agglomerate which doesn’t meet standards of industrial quality. It is possible to decompose NH3 into Nbreaking bonds more easily than N2, and H2 decomposed may hinder the formation of MgO. Thus, ammonia gases can be used as 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 analysis, liquid ammonia can react with magnesium powder much more quickly than nitrogen to produce magnesium nitride. The best quality magnesium nitride, with homogeneous and pure powder particles can be produced at 600 and ammonia in 1 hour. It is then heated up to 800, ammonia flow rate of about 500ml/min and the nitriding period of 1 hour.
