What is Magnesium-Nitride?
Magnesium Nitride, is an inorganic compound that has the chemical formula Mg3N2. It's part the Cubic Crystal System. At room temperature, pure magnesium nutridide is a yellowish-green powder with parts of impurities of magnesium oxide is grayish white.
The magnesium nitride's molar mass is 100.95g/mol. Their density stands at 2.712g/cm3. Magnesium Nitride is completely dissolvable in water and acid but is only partially dissolved in the ethanol and ether.
The melting point for magnesium nitride reaches 1500 degrees. Magnesium Nitride, like many metal nitrides reacts with water to create ammonia. It is frequently used as a catalyst. React with acid or nonmetallic oxides to create ammonium salts as well as magnesium salts.
Magnesium Nitride is a natural ceramic nature. Magnesium-nitride has superior corrosion resistance and greatly enhances production efficiency. Magnesium nitride has also high thermal conductivity as well with high corrosion resistance and resistance to temperature. Magnesium is also of great importance because it is used as a catalyst during the creation of boron nitrogen.
What is Magnesium Nitride Used For?
1. A catalyst used to create the nitride elements with high hardness and thermal conductivity. It is also a good choice for corrosion resistance, wear resistance and resistant to high temperatures. In the first successful synthesis of cubic boron nitride it was the catalyst that was used, magnesium nitride.
2. This is a high strength steel Smelting additives. Magnesium Nitride (Mg3N2) is a substitute for the magnesium that has been desulphurized for construction smelting, which is beneficial for increasing the density, strength of the steel, as well as the tension and bearing force of steel. Additionally, the use of magnesium Nitride (Mg3N2) desulfurization, can lessen the amount of additives, thereby helping to lower the cost of production for construction steel.
3. The use of ceramic is to prepare specific materials;
4. For the manufacture of special alloy foaming agent;
5. Glass that is specially made to be used in the manufacturing process;
6. For crosslinking with catalytic polymers
7. For the recycling of nuclear waste;
How to Make Magnesium Nitride?
The current preparation methods of magnesium nitride involve direct reaction method of magnesium powder with nitrogen, method of reaction of the nitrogen with magnesium in nitrogen plasma flow, magnesium coil explosion method in nitrogen atmosphere Chemical gas at low pressure process, self-propagating high temperature synthesis method nano magnesium nitride method of synthesis and more.
Recently, G. Soto et al. created amorphous magnesium nitride film that had different Mg/N ratios Si substrates within a molecular-nitrogen environment using Deposition using pulses of laser. These methods limit the production of industrial magnesium nitride due to their high costs, the lengthy process, complex equipment operation, or low yields for magnesium Nitride.
While the direct reaction of magnesium powder and nitrogen can have an industrial use, the creation of magnesium nitride powder requires higher temperatures for reaction and a longer reaction time. Furthermore, 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. NH3 can be decomposed into Nthat has broken bonds quicker than N2 and the decomposed H2 can block the formation of MgO, so ammonia gas can be used as a nitrogen source. Chen Faqin et al. Utilizing liquid ammonia as the nitrogen source for the preparation of magnesium nitride in the form of powder via direct the nitriding process of magnesium powder. The following conclusions could be drawn from thermodynamic analysis, liquid ammonia is able to react with magnesium powder far more easily than nitrogen in the preparation of magnesium nitride. Good quality magnesium nitride powder with the highest purity and uniform particles can easily be prepared at 600 and ammonia in 1h, then heated to 800degrees, with an ammonia flow rate of 500ml/min with an nitriding duration of 1h.
