What is Magnesium-Nitride?

Magnesium nitride is an inorganic chemical compound with the chemical formula Mg3N2. It belongs to the quantum system of cubic crystals. At low temperatures, pure magnesium nutridide is a yellowish-green powder however, magnesium nitride that contains parts of magnesium oxide particles is grayish white.

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

The melting temperature of magnesium nitride reaches 1500 degrees. Magnesium nitrideis one of the metal nitrides, reacts water to form ammonia. It is commonly used as a catalyst. React with acid or aqueous nonmetallic oxides to form ammonium salts and magnesium salts.

Magnesium Nitride is a kind of ceramic nature. Magnesium Nitride has a high corrosion resistance and greatly increases productivity. Magnesium has high thermal conductivity, aswell having a high resistance to corrosion and resistance to temperature. Magnesium Nitride is of further significance as it's used as a catalyst used in the creation of boron nitrogen.

What is Magnesium nitride Used for?

1. It is used as a catalyst to creating the nitride elements with high hardness with high thermal conductivity wear resistance, corrosion resistance and extremely high resistance to temperature. In the first successful creation of cubic boron nitride, it was the catalyst that was used, magnesium Nitride.

2. It is used for steel with high strength Smelting additives. Magnesium nitride (Mg3N2) is a substitute for desulphurized magnesium during construction steel melts, which is helpful to increase the density strength tension, and bearing force of steel. Furthermore, the usage of magnesium nitride (Mg3N2) desulfurization can reduce the amount of additives, which can help reduce the production cost of construction steel.

3. For the preparation of special ceramic materials;

4. For the manufacture of special alloy foaming agent;

5. To make special glass

6. To crosslink catalytically-linked polymers.

7. To recycle nuclear waste;

How do I Make Magnesium Nitride?

At present, the principal preparation methods of magnesium nitride comprises direct reaction method for magnesium powder using nitrogen, the method for resolving magnesium and nitrogen in nitrogen plasma flow using a magnesium coil blast method in nitrogen atmosphere the low pressure chemical gas complementing product method, self-propagating high temperature synthesis technique, the synthesis of nano magnesium as well as other methods.

Recently, G. Soto et al. made amorphous magnesium oxide films that had different Mg/N ratios Si substrates in a nitrogen molecular atmosphere by Deposition using pulses of laser. These methods are limited in their industrial application due to costs, lengthy processes complicated equipment operation or low yield of magnesium Nitride.

Although the direct reaction between magnesium powder with nitrogen has economic value, the production of magnesium nitride requires more heat and a longer response time. In addition, the shape of the powder is insufficient and easy to disperse, which doesn't meet requirements for industrial quality. In the case of NH3, it can be broken down into Nwith broken bonds more easily than N2, and the decomposed H2 could hinder the formation of MgO. Therefore, ammonia gas can be used as the nitrogen source. Chen Faqin et al. Utilizing liquid ammonia as the nitrogen source to prepare magnesium nitride via direct nitriding of magnesium powder. The following conclusions can be drawn: Based on thermodynamic analysis, liquid ammonia could react with magnesium powder faster than nitrogen to produce magnesium nitride; High quality magnesium nitride powder that has excellent purity and uniform particles can be made at 600 degrees Celsius and in ammonia-based atmosphere for 1 h, then heated up to 800degrees, with an ammonia flow rate of about 500ml/min and Nitriding time of 1h.
