What is Magnesium Nitride?
Magnesium nitride is an inorganic compound having the chemical formula Mg3N2. It's part a cube crystal system. At the temperature of room, pure magnesium nutridide is a yellowish-green powder however, magnesium nitride that contains the impurities of magnesium oxide is grayish white.
The magnesium nitride's molar mass is 100.95g/mol. In terms of density, it is 2.712g/cm3. Magnesium Nitride is completely dissolved in acid and water, but it is partially dissolved in the ether and ethanol.
The melting temperature of magnesium nitride lies at 1500 degrees. Magnesium Nitride, along with other metal nitrides, reacts with water to make ammonia. It is frequently used as a catalyst. It reacts with acid or nonmetallic oxides to create ammonium salts and magnesium salts.
Magnesium nitride is ceramic in nature. Magnesium nitride exhibits high corrosion resistance and greatly increases production efficiency. Magnesium has high thermal conductivity, as well being resistant to corrosion and resistance to temperature. Magnesium is also of great importance as it's utilized as a catalyst for chemical synthesis of boron.
What is Magnesium Nitride Used For?
1. Used as a catalyst when make the nitride out of other elements that have high hardness and thermal conductivity. It is also a good choice for wear resistance, corrosion resistance, and very high-temperature resistance. The first successful creation of cubic boron nitride, one catalyst involved was magnesium Nitride.
2. It is used for steel with high strength alloys for smelting. Magnesium nitride (Mg3N2) replaces desulphurized magnesium during construction steel melts, which is helpful for increasing the density, strength tension, and bearing force of steel. In addition, the process of magnesium nitride (Mg3N2) desulfurization, may lower the amount of other additivesand help reduce the production cost of construction steel.
3. Used to prepare special ceramic materials;
4. For the manufacturing of a specific alloy foaming agent;
5. For the production of special glass
6. Catalytic polymer crosslinking
7. For the recycling of radioactive waste
How Do You Produce Magnesium Nitride?
Presently, the major methods for making magnesium nitride consist of direct reaction method for magnesium powder using nitrogen, the method for resolving magnesium with nitrogen in nitrogen plasma flow methods for magnesium coils in nitrogen atmosphere low pressure chemical gas supplementing method for product, self-propagating high temperature process for synthesis, nano magnesium nitride synthesis technique, and so on.
Recently, G. Soto et al. created amorphous magnesium nitride film with different ratios of Mg:N on Si substrates in a nitrogen-based molecular environment by the use of pulse-laser deposition. These techniques restrict the industrial production of these films due to the high price, lengthy process complex operation of equipment or a lower yield of magnesium nitride.
Although the direct reaction of magnesium powder with nitrogen has industrial value, the production of magnesium nitride-based powder requires more heat and a longer response time. In addition, the form of the particles is a bit lopsided and easy to form agglomerates, that's why they don't meet the demands of industrial quality. In the process of decomposition, NH3 can form Nbreaking bonds more easily than N2, and decomposed H2 may stop the formation of MgO. So, ammonia could be utilized as a nitrogen source. Chen Faqin et al. utilized 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 can be drawn: By thermodynamic analysis, liquid ammonia may react with magnesium powder more easily than nitrogen to produce magnesium nitride. The best quality magnesium nitride, with an extremely high purity and uniform particles can be prepared at 600 degrees Celsius and in ammonia-based atmosphere for 1 hour. It is then heated up to 800°C, with an ammonia flow rate of 500ml/min , and an nitriding duration of 1h.
