What is Magnesium-Nitride?
Magnesium nitride, is an inorganic substance with the chemical formula Mg3N2. It's part a cubic crystal structure. At room temperature, pure magnesium nutridide is yellow-green, but magnesium nitride containing some magnesium oxide particles is grayish white.
The magnesium nitride's molar mass is 100.95g/mol. Its density 2.712g/cm3. Magnesium Nitride is completely dissolved in water and acid, but is only partially dissolved in Ether and ethanol.
The melting point of magnesium nitride reaches 1500 degrees. Magnesium Nitride, just like many metal nitrides, reacts water to create ammonia. A catalyst is often employed. React with acid or aqueous nonmetallic oxidants to form ammonium salts as well as magnesium salts.
Magnesium nitride , a type of ceramic, is found in nature. Magnesium nitride is highly resistant to corrosion resistance, and significantly improves production efficiency. Magnesium nitride has also high thermal conductivity, as well having a high resistance to corrosion and temperature resistance. Magnesium Nitride is also of significant importance as it's utilized as a catalyst during the creation of boron nitrogen.
What is Magnesium Nitride used for?
1. Used as a catalyst when creating the nitride elements that have high hardness as well as high thermal conductivity. corrosion resistance, wear resistance and extreme temperature resistance. In the first successful chemical synthesis of cubic-boron nitride an active catalyst came from magnesium nitride.
2. Used for high strength steel alloys for smelting. Magnesium nitride (Mg3N2) is a substitute for the magnesium that has been desulphurized for construction melts, which is helpful in increasing the density strength that, tension and bearing capacity of steel. In addition, the use of magnesium nitride (Mg3N2) desulfurizationcould reduce the quantity of other additives, thus helping to reduce the production cost of construction steel.
3. It is used to prepare special ceramic materials;
4. For the manufacturing of a specific alloy foaming agent
5. For manufacturing special glass;
6. Catalytic polymer crosslinking
7. To reuse radioactive waste
How to Make Magnesium Nitride?
Presently, the primary methods for making magnesium nitride consist of direct reaction method of magnesium powder with nitrogen, method of reaction of magnesium with nitrogen inside nitrogen plasma flow, magnesium coil explosion method in nitrogen atmosphere Chemical gas at low pressure process, self-propagating high temperature method for synthesis, nano magnesium nitride synthesis technique, etc.
Recently, G. Soto et al. created amorphous magnesium Nitride films that had different Mg/N ratios Si substrates in a molecular nitrogen-filled environment by Deposition using pulses of laser. These techniques restrict their production in the industrial sector due to costs, lengthy processes complicated equipment operation or low yield of magnesium Nitride.
While the direct reaction of magnesium powder with nitrogen is of commercial value, the manufacture of magnesium powder requires more heat and a longer reaction time. Furthermore, the particle's shape is not perfect and easy to agglomerate that is not able to meet the standards of industrial quality. NH3 can be decomposed into Nthat has broken bonds faster than N2 and the decomposed H2 will slow the growth of MgO, which is why ammonia gas can be used as the nitrogen source. Chen Faqin et al. utilized liquid ammonia as a nitrogen source for the preparation of magnesium nitride by direct nitriding of magnesium powder. The following conclusions could be drawn: From a thermodynamic analysis, liquid ammonia could react with magnesium powder more readily than nitrogen in the preparation of magnesium nitride. High-quality magnesium nitride in an extremely high purity and uniform particles is made by heating it to 600 and an ammonia atmosphere for 1 h, then heated up to 800, ammonia flow rate is 500ml/min. an nitriding duration of 1h.
