What is Magnesium Nitride?
Magnesium Nitride, is an inorganic molecule with the chemical formula Mg3N2. It's part the cubic crystal system. At temperatures at room temperature, pure magnesium nutridide is a bright yellow-green color with parts of magnesium oxide impurities is greyish white.
The Molar mass of magnesium nutride is 100.95g/mol. In terms of density, it is 2.712g/cm3. Magnesium Nitride is completely dissolved in water and acid but partially dissolved in the ether and ethanol.
The melting point of magnesium nitride ranges from 1500 to 1500 degrees. Magnesium, like other metal nitrides, reacts with water and produces ammonia. Commonly used as a catalyst. React with acid or nonmetallic oxides in order to produce ammonium salts and magnesium salts.
Magnesium nitride is ceramic in nature. Magnesium-nitride has superior corrosion resistance, which greatly increases production efficiency. Magnesium has high thermal conductivity as well being highly resistant to corrosion as well as resistance to temperature. Magnesium Nitride has an additional importance due to its usage as a catalyst for the production of boron-Ni.
What Is Magnesium-Nitride Used For?
1. Utilized as a catalyst in order to creating the nitride elements that have high hardness along with high thermal conductivity corrosion resistance, wear resistance and resistant to high temperatures. The first successful production of cubic boron-nitride, its catalyst was magnesium Nitride.
2. Utilized for high-strength steel Smelting additives. Magnesium Nitride (Mg3N2) replaces desulphurized magnesium used in construction steel in smelting. This helps in increasing the density strength in tension and bearing power of steel. Additionally, the use of magnesium Nitride (Mg3N2) desulfurizationmay lower the amount of other additives, thus helping to reduce the costs of production for construction steel.
3. For the preparation of special ceramic materials;
4. for the manufacture of a particular alloy foaming agent
5. Glass that is specially made to be used in the manufacturing process;
6. To crosslink catalytically-linked polymers.
7. For the recycling of nuclear waste
How do I Make Magnesium Nitride?
At present, the main preparation methods of magnesium nitride are direct reaction method of magnesium powder with nitrogen, the method for resolving magnesium and nitrogen in nitrogen plasma flow methods for magnesium coils in nitrogen atmosphere, low pressure chemical gas process, self-propagating high temperature process for synthesis, nano magnesium nitride synthesizer as well as other methods.
Recently, G. Soto et al. constructed amorphous magnesium nutride films with different Mg:N ratios on Si substrates in a molecular nitrogen environment through in-situ pulse laser deposition. This method limits their production for industrial use due to costs, lengthy processes complicated equipment operation or low yield of magnesium nutride.
Although the direct reaction between magnesium powder with nitrogen holds industrial value, the production of magnesium nitride powder needs higher reaction temperature and longer processing time. The form of the particles is a bit lopsided and easy to agglomerate, which doesn't meet demands of industrial-grade quality. In the case of NH3, it can be broken down into Nwith broken bonds quicker than N2 and decomposed H2 may block the formation of MgO. As such, ammonia gas is an ideal nitrogen source. Chen Faqin et al. utilized liquid ammonia as a nitrogen source for the preparation of magnesium nitride material by direct nitriding of magnesium powder. The following conclusions can be drawn: Through thermodynamic analysis, liquid ammonia can react with magnesium powder more easily than nitrogen, resulting in magnesium nitride. Good quality magnesium nitride powder that has homogeneous and pure powder particles can be produced at 600 and ammonia at 1 hour. Then, it's heated to 800°C, with an ammonia flow rate of 500ml/min , and the time for nitriding of 1h.
