What is Magnesium Nitride?
Magnesium Nitride is an inorganic substance with the chemical formula Mg3N2. It is a part of the cube crystal system. At the temperature of room, pure magnesium nutridide is yellow-green, but magnesium nitride containing a portion of impurities made of magnesium oxide is grayish white.
The molar mass of magnesium nitride is 100.95g/mol. In terms of density, it is 2.712g/cm3. Magnesium nitride dissolves completely in water and acid, but partially dissolved in Ether and ethanol.
The melting temperature of magnesium nitride ranges from 1500 to 1500 degrees. Magnesium Nitride, just like many metal nitrides, reacts water to create ammonia. It is often used as a catalyst. React with acidic or aqueous nonmetallic oxides , forming ammonium salts as well as magnesium salts.
Magnesium nitride is ceramic in nature. Magnesium Nitride has a high corrosion resistance and greatly improves productivity. Magnesium nitride also has high thermal conductivity, as well with high corrosion resistance and resistance to temperature. Magnesium nitride has another great significance due to its use as a catalyst used in the synthesizing of boron.
What is Magnesium Nitride used for?
1. A catalyst used to create the nitride elements that have high hardness with high thermal conductivity wear resistance, corrosion resistance, and high temperature resistance. The first successful production of cubic boron-nitride, one catalyst involved was magnesium Nitride.
2. The product is designed for use as high strength steel alloys for smelting. Magnesium Nitride (Mg3N2) is a substitute for magnesium desulphurized in construction steel Smelting, which can help to improve the density, strength that, tension and bearing capacity of steel. Additionally, the use of magnesium nitride (Mg3N2) desulfurizationmay lower the amount of other additives, thereby helping to lower the cost of manufacturing construction steel.
3. For the preparation of special ceramic materials;
4. For the manufacturing of a specific alloy foaming agent;
5. Special glass for manufacturing;
6. Crosslinking of catalytic polymers;
7. For the recycling of nuclear waste
How to Make Magnesium Nitride?
The main methods for making magnesium nitride are direct reactions method for magnesium powder using nitrogen, the reaction method of magnesium with nitrogen using nitrogen plasma flow and the magnesium coil explosion method in nitrogen atmosphere low pressure chemical gas supplementing method for product, self-propagating high temperature method for synthesis, nano magnesium nitride synthesizer and many more.
Recently, G. Soto et al. prepared amorphous magnesium nitride films that have different Mg:N ratios Si substrates in a molecular nitrogen environment through Laser pulse deposition. These methods are limited in their industrial production due to the cost of production, lengthy process as well as the complexity of operating equipment or a lower yield of magnesium nutride.
Although the direct reaction of magnesium powder and nitrogen can have an industrial use, the creation of magnesium nitride-based powder requires more heat and a longer reaction time, and the shape of the particles are not ideal and easy to agglomerate, which can not meet the demands of industrial quality. In the case of NH3, it can be broken down into Nbreaking bonds quicker than N2 and the decomposed H2 could block the formation of MgO. So, ammonia could be utilized as a nitrogen source. Chen Faqin et al. utilized liquid ammonia for nitrogen source to make magnesium nitride powder through direct Nitriding of magnesium powder. The following conclusions can be drawn: Using thermodynamic analyses, liquid ammonia could react with magnesium powder much more quickly than nitrogen to make magnesium nitride. The best quality magnesium nitride that is consistent and high purity particles can easily be prepared at 600, and then ammonia for 1 h, then heated up to 800, ammonia flow rate of 500ml/min as well as one hour of nitriding.
