What is Magnesium Nitride?

Magnesium Nitride is an inorganic compound with the chemical formula Mg3N2. It's part a quantum system of cubic crystals. At room temperature, pure magnesium nutridide is yellow-green However, magnesium nitride that has portions of magnesium oxide impurities can be grayish white.

The Molar mass of magnesium Nitride is 100.95g/mol. Their density stands at 2.712g/cm3. Magnesium nitride dissolves completely in water and acid but partially dissolved in both ethanol and ether.

The melting point for magnesium nitride is 1500 °. Magnesium Nitride, along with other metal nitrides, reacts water and produces ammonia. Often used as a catalyst. They react with acid or nonmetallic oxides in order to produce ammonium salts and magnesium salts.

Magnesium nitride , a type of ceramic, is found in nature. Magnesium has excellent corrosion resistance and significantly increases productivity. Magnesium also has high thermal conductivity, aswell as high corrosion resistance and temperature resistance. Magnesium nitride has another great importance because it is used as a catalyst during the formation of boron.

What Do You Use Magnesium Nitride For?

1. Use as a catalyst to prepare the nitride of other elements with high hardness as well as high thermal conductivity. corrosion resistance, wear resistance, and very high-temperature resistance. The first successful chemical synthesis of cubic-boron nitride, it was the catalyst that was used, magnesium nitride.

2. This is a high strength steel additions to smelting. Magnesium nitride (Mg3N2) is a substitute for desulphurized magnesium in construction Smelting, which can help in increasing the density, strength, tension and bearing force of steel. In addition, the process of magnesium Nitride (Mg3N2) desulfurization can decrease the amount of other additives, which can help reduce the production cost of construction steel;

3. This is used to make special ceramic materials;

4. To make a special alloy foaming agent

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

6. To crosslink catalytically-linked polymers.

7. For the recycling of nuclear waste;

How to Produce Magnesium Nitride?

The main methods for making magnesium nitride are direct reaction method for magnesium powder using nitrogen, reaction method of magnesium with nitrogen in nitrogen plasma flow, magnesium coil explosion method in nitrogen atmosphere the low pressure chemical gas in conjunction with the product method, self-propagating high temperature synthesis method, nano magnesium nitride synthesis technique and many 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 using Deposition using pulses of laser. These techniques limit their industrial production because of high cost, long process, complex equipment operation, or a lower yield of magnesium oxide.

While the direct reaction of magnesium powder using nitrogen has industrial value, the production of magnesium nitride powder requires higher temperature for the reaction and a long response time. In addition, the particle's shape is not perfect and easy to agglomerate, which doesn't meet requirements for industrial quality. It is possible to decompose NH3 into N- with broken bonds faster than N2 and the decomposed H2 can hinder the formation 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 prepare magnesium nitride powder through direct nitriding of magnesium powder. The following conclusions can be drawn: By thermodynamic analyses, liquid ammonia could react with magnesium powder more readily than nitrogen to prepare magnesium nitride. Good quality magnesium nitride powder that has consistent and high purity particles can be made at 600 degrees Celsius and in ammonia-based atmosphere for 1 hour, and then heated to 800, ammonia flow rate is 500ml/min. nitriding time of 1h.
