What is Magnesium Nitride
What is Magnesium Nitride?
Magnesium Nitride, is an inorganic chemical compound with the chemical formula Mg3N2. It is part of the quantum system of cubic crystals. At temperatures of room temperature, the pure magnesium nutride is a color of yellow and green but magnesium nitride with parts of magnesium oxide particles is grayish white.
The Molar mass of magnesium oxide is 100.95g/mol. Density is 2.712g/cm3. Magnesium Nitride is totally dissolved in water and acid, but is only partially dissolved in the ether and ethanol.
The melting point of magnesium nitride can be found at 1500 degrees. Magnesium Nitride, just like many metal nitrides reacts with water to produce ammonia. Often used as a catalyst. React with acidic or aqueous nonmetallic oxides , forming ammonium salts as well as magnesium salts.
Magnesium Nitride is a kind of ceramic 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 is also of significant importance because it is used as a catalyst to aid in the chemical synthesis of boron.
What is Magnesium Nitride Used For?
1. Use as a catalyst to making nitride from other elements that have high hardness as well as high thermal conductivity, corrosion resistance, wear resistance and very high-temperature resistance. The first successful synthesis of cubic boron nitride, it was the catalyst that was used, magnesium Nitride.
2. Utilized for high-strength steel for smelting. Magnesium nitride (Mg3N2) is a substitute for desulphurized magnesium in construction smelting, which is beneficial to increase the density strength, tension and bearing force of steel. In addition, the process of magnesium Nitride (Mg3N2) desulfurizationcould reduce the amount of components, thereby helping lower the cost of production for construction steel.
3. It is used to prepare special ceramic materials;
4. To make a special alloy foaming agent;
5. Special glass is made for the purpose of manufacturing;
6. For crosslinking catalytically produced polymers
7. To reuse nuclear waste
How do I Make Magnesium Nitride?
Presently, the most popular methods for making magnesium nitride include direct reaction method of magnesium powder with nitrogen, the reaction method of magnesium with nitrogen inside nitrogen plasma flow in the form of a magnesium coil explosion in nitrogen atmosphere as well as low-pressure chemical gas in conjunction with the product method, self-propagating high temperature synthesis procedure, nano magnesium nitride synthesis technique, etc.
Recently, G. Soto et al. have prepared amorphous magnesium nutride films featuring different Mg:N ratios Si substrates in a molecular nitrogen-filled environment by pulse laser deposition. These techniques limit their production for industrial use due to high cost, long process complex operation of equipment or a lower yield of magnesium Nitride.
While 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. Additionally, the shape of the powder is insufficient and easy to agglomerate which does not meet specifications of industrial quality. The NH3 is decomposed into Nthat has broken bonds more easily than N2, and the H2 that is decomposed can prevent the formation MgO. Therefore, 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 could be drawn: By thermodynamic analyses, liquid ammonia could react with magnesium powder much more quickly than nitrogen to prepare magnesium nitride; High quality magnesium nitride powder that has the highest purity and uniform particles is prepared by heating to 600 degrees Celsius and in ammonia-based atmosphere for 1h, after which it is heated to 800, ammonia flow rate is 500ml/min. an nitriding duration of 1h.
