What is Magnesium Nitride?
Magnesium nitride, is an inorganic molecule with the chemical formula Mg3N2. It’s part a cubic crystal system. At ambient temperature, magnesium nutridide is yellow-green, but magnesium nitride containing some magnesium oxide impurities is greyish white.
The Molar mass of magnesium-nitride is 100.95g/mol. The density of the mineral is 2.712g/cm3. Magnesium Nitride is totally dissolved in water and acid, however it is partially dissolved by Ether and ethanol.
The melting point for magnesium nitride can be found at 1500 degrees. Magnesium nitride, like many metal nitrides, reacts water to produce ammonia. Often used as a catalyst. React with acidic or aqueous nonmetallic oxides and form ammonium salts and magnesium salts.
Magnesium Nitride is a ceramic substance in nature. Magnesium Nitride has a high corrosion resistance and greatly enhances the efficiency of production. Magnesium has high thermal conductivity as well being highly resistant to corrosion as well as temperature resistance. Magnesium Nitride has an additional importance due to its usage as a catalyst for synthesizing of boron.
What is Magnesium Nitride Used For?
1. Utilized as a catalyst in order to create the nitride elements that have high hardness as well as high thermal conductivity. corrosion resistance, wear resistance, and the ability to withstand high temperatures. In the first successful formula for cubic boron, this catalyst is magnesium nitride.
2. The product is designed for use as high strength steel smelting additives. Magnesium Nitride (Mg3N2) is a substitute for desulphurized magnesium in construction in smelting. This helps in increasing the density strength as well as the bearing force of steel. Additionally, the use of magnesium Nitride (Mg3N2) de-sulfurization can lessen the amount of ingredients, and thus help to reduce the costs of production for construction steel;
3. It is used to prepare special ceramic materials;
4. In the process of making a special alloy foaming agent
5. Glass that is specially made to be used in the manufacturing process;
6. Catalytic polymer crosslinking
7. To reuse nuclear waste;
How Do You Produce Magnesium Nitride?
The current methods for making magnesium nitride involve direct reaction method of magnesium powder with nitrogen, the method for resolving magnesium and nitrogen in nitrogen plasma flow, magnesium coil explosion method in nitrogen atmosphere low pressure chemical gas complementary product method, self-propagating high temperature synthesis technique, nano magnesium nitride synthesizer, and so on.
Recently, G. Soto et al. have prepared amorphous magnesium nutride films featuring different Mg:N ratios Si substrates in a molecular nitrogen atmosphere through the use of pulse-laser deposition. This method limits the industrial production of these films due to costly costs, long processing complex operation of equipment or low yields of magnesium oxide.
The direct reaction of magnesium powder with nitrogen holds commercial value, the manufacture of magnesium nitride powder needs greater temperature of reaction as well as a longer reaction time, and the shape of the particles are not ideal and easy to agglomerate, and therefore, does not meet the requirements for industrial quality. In the process of decomposition, NH3 can form Nwhich has broken bonds faster than N2 and the decomposed H2 will interfere with the formation process of MgO. This is why ammonia could be used as the nitrogen source. Chen Faqin et al. used liquid ammonia as nitrogen source to make magnesium nitride by direct nutriding of magnesium. The following conclusions could be drawn: By thermodynamic analyses, liquid ammonia could react with magnesium powder more easily than nitrogen for the production of magnesium nitride. The best quality magnesium nitride with excellent purity and uniform particles can be made at 600 and ammonia pressure for 1hand then heated to 800°C, with an ammonia flow rate 500ml/min and an nitriding duration of 1h.
