What is Magnesium Nitride?
Magnesium Nitride is an inorganic compound with the chemical formula Mg3N2. It is part of the cluster of cubic crystals. At ambient temperature, magnesium nitride is a yellow-green powder, but magnesium nitride containing portions of magnesium oxide particles is grayish white.
The Molar mass of magnesium nitride is 100.95g/mol. Its density 2.712g/cm3. Magnesium nitride is completely dissolved in acid and water, but is dissolvable in Ether and ethanol.
The melting temperature of magnesium nitride lies at 1500 degrees. Magnesium Nitride, as with many metal nitrides reacts with water to create ammonia. Commonly used as a catalyst. They react with acid or nonmetallic oxides that result in ammonium salts as well as magnesium salts.
Magnesium nitride , a type of ceramic, is found in nature. Magnesium is abrasion-resistant material that has excellent resistance, and significantly improves the efficiency of production. Magnesium is also a great material for thermal conductivity as well with high corrosion resistance and temperature resistance. Magnesium Nitride is of further significance because it serves as a catalyst process of making boron nitrogen.
What Do You Use Magnesium Nitride For?
1. As a catalyst, it is used to you are preparing the nitride of other elements with high hardness and high thermal conductivity. It also provides corrosion resistance, wear resistance, and resistant to high temperatures. In the first successful synthesis of cubic boron nitride it was the catalyst that was used, magnesium Nitride.
2. A high-strength steel alloys for smelting. Magnesium Nitride (Mg3N2) replaces desulphurized magnesium in construction steel melts, which is helpful to increase the density strength tension, and bearing force of steel. In addition, the application of magnesium Nitride (Mg3N2) desulfurizationcould reduce the use of other additives, thereby helping to reduce the costs of production for construction steel.
3. Useful for preparing special ceramic materials;
4. To make a special alloy foaming agent;
5. For the production of special glass
6. To crosslink catalytically-linked polymers.
7. To reuse nuclear waste
How Do You Produce Magnesium Nitride?
The main preparation methods of magnesium nitride comprises direct reaction method for magnesium powder using nitrogen, reaction method of magnesium with nitrogen within nitrogen plasma flow and the magnesium coil explosion method in nitrogen atmosphere the low pressure chemical gas supplementing method for product, self-propagating high temperature synthesis method, nano magnesium nitride method of synthesis and more.
Recently, G. Soto et al. produced amorphous magnesium-nitride films with different ratios of Mg:N on Si substrates in a molecular nitrous environment using Laser pulse deposition. These techniques limit the industrial production of these films due to the cost of production, lengthy process as well as the complexity of operating equipment or the low yield of magnesium nitride.
Although the direct reaction of magnesium powder using nitrogen has economic value, the production from magnesium nitride needs more heat and a longer reaction time. Furthermore, the shape of the particles are not ideal as well as easy to agglomerate which isn't able to meet needs of industrial grade. In the process of decomposition, NH3 can form Nand N2 - with broken bonds much more quickly than N2 and the decomposed H2 could interfere with the formation process of MgO. This is why ammonia can be used as the nitrogen source. Chen Faqin et al. used liquid ammonia to serve as nitrogen source to prepare magnesium nitride material by direct the nitriding process of magnesium powder. The following conclusions could be drawn: Through thermodynamic analyses, liquid ammonia could react with magnesium powder more readily than nitrogen to produce magnesium nitride; High quality magnesium nitride with good purity and uniform particles can easily be prepared at 600 and ammonia in 1h, after which it is heated to 800, ammonia flow rate is 500ml/min. an nitriding duration of 1h.
