What is Magnesium Nitride?

Magnesium nitride is an organic compound with the chemical formula Mg3N2. It belongs to the cluster of cubic crystals. At the temperature of room, pure magnesium nutridide is a yellowish-green powder however, magnesium nitride that contains part of magnesium oxide particles is grayish white.

The Molar mass of magnesium nutride is 100.95g/mol. Its density 2.712g/cm3. Magnesium nitride dissolves completely in water and acid, but is partially dissolvable when mixed with Ether and ethanol.

The melting point for magnesium nitride lies at 1500 degrees. Magnesium nitride, like many metal nitrides water to create ammonia. It is often used as a catalyst. React with acid , or aqueous nonmetallic oxides to create ammonium salts as well as magnesium salts.

Magnesium nitride is ceramic in nature. Magnesium Nitride has a high corrosion resistance and greatly increases the efficiency of production. Magnesium also has high thermal conductivity as well with high corrosion resistance and temperature resistance. Magnesium Nitride is also of significant significance as it's used as a catalyst for the process of making boron nitrogen.

What Do You Use Magnesium Nitride For?

1. This is used as a catalyst preparation of nitride compounds from other elements that have high hardness as well as high thermal conductivity, wear resistance, corrosion resistance and the ability to withstand high temperatures. The first successful synthesizing of cubic boron, The catalyst used was magnesium nitride.

2. Utilized for high-strength steel for smelting. Magnesium nitride (Mg3N2) replaces magnesium desulphurized in construction steel in smelting. This helps for increasing the density, strength as well as the bearing force of steel. In addition, the process of magnesium nitride (Mg3N2) desulfurization can reduce the quantity of other additives, which can help lower the cost of manufacturing construction steel;

3. Used to prepare special ceramic materials;

4. For the production of a special alloy foaming agent

5. For manufacturing special glass;

6. For crosslinking with catalytic polymers

7. To reuse radioactive waste

How to Make Magnesium Nitride?

Presently, the major preparation methods of magnesium nitride are direct reactions method for magnesium powder using nitrogen, method of reaction of the nitrogen with magnesium in nitrogen plasma flow as well as the method for the explosion of magnesium coils in nitrogen atmosphere as well as low-pressure chemical gas in conjunction with the product method, self-propagating high temperature process for synthesis, nano magnesium nitride method of synthesis for example.

Recently, G. Soto et al. created amorphous magnesium nitride film with different Mg:N ratios on Si substrates in a nitrogen molecular atmosphere by pulse laser deposition. These techniques limit the industrial production of these films due to high cost, long process or complex equipment operation or low yield of magnesium oxide.

The direct reaction of magnesium powder and nitrogen can have significant industrial potential, the making of magnesium nitride powder needs more heat and a longer reaction time, and the shape of particles is incomplete and easy to aggregate, which doesn't meet demands of industrial-grade quality. The NH3 is decomposed into N- with broken bonds quicker than N2 and the decomposed H2 could block the formation of MgO, so ammonia gas can be used as a nitrogen source. Chen Faqin et al. employed liquid ammonia as a nitrogen source for the preparation of magnesium nitride in the form of powder via direct Nitriding of magnesium powder. The following conclusions can be drawn: From a thermodynamic analyses, liquid ammonia could react to magnesium powder more efficiently than nitrogen, resulting in magnesium nitride; High quality magnesium nitride in homogeneous and pure powder particles can be prepared at 600, and then ammonia for 1 hour. It is then heated up to 800°C, with an ammonia flow rate of 500ml/min , and an nitriding duration of 1h.
