What is Magnesium-Nitride?
Magnesium nitride, is an inorganic compound with the chemical formula Mg3N2. It's particulate matter that is part of the cubic crystal structure. At ambient temperature, magnesium nitride is a yellow-green powder and magnesium nitride which contains an element of magnesium oxide particles is grayish white.
The molar mass of magnesium nitride is 100.95g/mol. Density is 2.712g/cm3. Magnesium Nitride is totally dissolved in water and acid, but partially dissolved in alcohol and ether.
The melting temperature of magnesium nitride lies at 1500 degrees. Magnesium nitrideis one of the metal nitrides water and produces ammonia. It is frequently used as a catalyst. React with acid and aqueous nonmetallic oxides to form ammonium salts as well as magnesium salts.
Magnesium Nitride is a natural ceramic nature. Magnesium nitride is highly resistant to corrosion resistance and greatly improves the efficiency of production. Magnesium also has high thermal conductivity, aswell in high corrosion resistance and resistance to temperature. Magnesium Nitride is of additional importance as it's utilized as a catalyst used in the synthesizing of boron.
What Is Magnesium-Nitride Used For?
1. Use as a catalyst to making nitride from other elements with high hardness as well as high thermal conductivity. wear resistance, corrosion resistance, and higher temperature resistance. The first successful creation of cubic boron nitride, The catalyst used was magnesium Nitride.
2. A high-strength steel for smelting. Magnesium Nitride (Mg3N2) is a substitute for desulphurized magnesium used in construction steel Smelting, which can help to increase the density strength in tension and bearing power of steel. In addition, the process of magnesium nitride (Mg3N2) desulfurization, may decrease the amount of other additives, thus helping to reduce the production cost of construction steel;
3. Utilized to make special ceramic materials;
4. For the manufacture of special alloy foaming agent
5. To make special glass
6. For crosslinking with catalytic polymers
7. To reuse nuclear waste;
How to Produce Magnesium Nitride?
The current preparation methods of magnesium nitride are direct reactions method for magnesium powder using nitrogen, reaction method of magnesium with nitrogen using nitrogen plasma flow and the magnesium coil explosion method in nitrogen atmosphere as well as low-pressure chemical gas as a complementary product method, self propagating high temperature synthesis procedure, nano magnesium nitride method of synthesis and many more.
Recently, G. Soto et al. created amorphous magnesium nitride film with different Mg/N ratios on Si substrates within a molecular-nitrogen environment through pulse laser deposition. This method limits their production in the industrial sector due to high cost, long process with complex equipment, or low yield of magnesium oxide.
While the direct reaction of magnesium powder and nitrogen has industrial benefits, the process of magnesium nitride requires greater reaction temperatures and a longer reaction times, and the form of the particles isn't perfect and easy to aggregate, that's why they don't meet the standards of industrial quality. N3 can be broken into N- with broken bonds more easily than N2, and decomposed H2 may inhibit the formation of MgO. This is why ammonia is an ideal nitrogen source. Chen Faqin et al. Utilizing liquid ammonia as the nitrogen source to prepare magnesium nitride powder by direct nitriding of magnesium powder. The following conclusions can be drawn: From a thermodynamic study, liquid ammonia might react with magnesium powder far more easily than nitrogen to produce magnesium nitride. High-quality magnesium nitride that is consistent and high purity particles is prepared by heating to 600 and ammonia pressure for 1h, then heated to 800°C, with an ammonia flow rate of 500ml/min , and Nitriding time of 1h.
