What is Magnesium Nitride?
Magnesium nitride is an inorganic compound having the chemical formula Mg3N2. It belongs to the cubic crystal system. At the temperature of room, pure magnesium Nitride is a yellow-green or green powder and magnesium nitride which contains parts of magnesium oxide impurities appears grayish white.
The Molar mass of magnesium nutride is 100.95g/mol. The density of the mineral is 2.712g/cm3. Magnesium Nitride is completely dissolvable in water and acid, however, it is partially dissolvable in ether and ethanol.
The melting temperature of magnesium nitride is 1500 degrees. Magnesium Nitride, along with other metal nitrides water to make ammonia. Sometimes, it is used as catalyst. They react with acid or nonmetallic oxidants to form ammonium salts as well as magnesium salts.
Magnesium Nitride is a clay-like substance found in nature. Magnesium-nitride has superior corrosion resistance and greatly increases productivity. Magnesium is also a great material for thermal conductivity, as well being high corrosion resistance as well as temperature resistance. Magnesium nitride also has a great significance since it's used as a catalyst for synthesizing of boron.
What is Magnesium Nitride Used For?
1. It is used as a catalyst to you are preparing the nitride of other elements that have high hardness and high thermal conductivity. It also provides corrosion resistance, wear resistance, and higher temperature resistance. In the first successful production of cubic boron-nitride, the catalyst was magnesium Nitride.
2. The product is designed for use as high strength steel and smelting additives. Magnesium nitride (Mg3N2) replaces desulphurized magnesium in construction Smelting, which can help in increasing the density, strength in tension and bearing power of steel. In addition, the use of magnesium nitride (Mg3N2) desulfurization, may lower the amount of other additives, helping to decrease the cost of production of construction steel.
3. Useful for preparing special ceramic materials;
4. To make a special alloy foaming agent;
5. For manufacturing special glass;
6. To crosslink catalytically-linked polymers.
7. To recycle nuclear waste
How do I Make Magnesium Nitride?
The main preparation methods of magnesium nitride involve direct reaction method of magnesium powder with nitrogen, the method for resolving magnesium with nitrogen using nitrogen plasma flow the method of magnesium coil explosion in nitrogen atmosphere Low pressure chemical gas as a complementary product method, self propagating high temperature synthesis procedure, nano magnesium nitride synthesis method and many more.
Recently, G. Soto et al. created amorphous magnesium nitride film featuring different Mg:N ratios Si substrates within a molecular-nitrogen environment using pulse laser deposition. These techniques limit their production in the industrial sector due to expensive costs, long processes complex operation of equipment or low yields for magnesium nutride.
Although the direct reaction between magnesium powder and nitrogen can have significant industrial potential, the making of magnesium nitride requires higher temperature for the reaction and a long response time. In addition, the shape of the particles are not ideal and easy to aggregate, which doesn't meet demands of industrial-grade quality. NH3 can be decomposed into N- with broken bonds quicker than N2 and the H2 that is decomposed can block the formation of MgO, so ammonia gas can be used as a nitrogen source. Chen Faqin et al. used liquid ammonia to serve as nitrogen source to make magnesium nitride by direct the nitriding process of magnesium powder. The following conclusions can be drawn: By thermodynamic study, liquid ammonia might react with magnesium powder faster than nitrogen in the preparation of magnesium nitride. Premium magnesium nitride that is homogeneous and pure powder particles can be prepared at 600 and ammonia atmosphere for 1 hour. It is then heated up to 800, ammonia flow rate of 500ml/min with the nitriding process takes 1 hour.
