What is Magnesium-Nitride?
Magnesium Nitride, is an inorganic molecule with the chemical formula Mg3N2. It is a part of the cubic crystals system. At temperatures at room temperature, pure magnesium nutridide is a bright yellow-green color with part of 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 acid and water, but is partially dissolvable when mixed with alcohol and ethanol.
The melting temperature of magnesium nitride is 1500 °. Magnesium nitrideis one of the metal nitrides, reacts water to produce ammonia. It is often used as a catalyst. React with acidic or aqueous nonmetallic oxides to create ammonium salts and magnesium salts.
Magnesium Nitride is a ceramic substance in nature. Magnesium nitride is highly resistant to corrosion resistance and significantly increases productivity. Magnesium nitride also has high thermal conductivity, aswell being highly resistant to corrosion as well as temperature resistance. Magnesium Nitride has an additional importance due to its usage as a catalyst to aid in the creation of boron nitrogen.
What is Magnesium nitride Used for?
1. Used as a catalyst when you are preparing the nitride of other elements with high hardness along with high thermal conductivity corrosion resistance, wear resistance, and very high-temperature resistance. In the first successful formula for cubic boron its catalyst was magnesium Nitride.
2. It is used for steel with high strength for smelting. Magnesium Nitride (Mg3N2) is a substitute for desulphurized magnesium during construction steel Smelting, which can help for increasing the density, strength in tension and bearing power of steel. In addition, the application of magnesium Nitride (Mg3N2) desulfurizationwill reduce the amount of other additives, thereby helping to decrease the cost of production of construction steel.
3. It is used to prepare special ceramic materials;
4. For the production of a special alloy foaming agent
5. To make special glass
6. For catalytic crosslinking of polymers
7. To reuse nuclear waste;
How Do You Produce Magnesium Nitride?
The current preparation methods of magnesium nitride consist of direct reaction method of magnesium powder with nitrogen, the reaction method of magnesium with nitrogen inside nitrogen plasma flow using a magnesium coil blast method in nitrogen atmosphere low pressure chemical gas complementary product method, self-propagating high temperature method for synthesis, nano magnesium nitride method of synthesis and many more.
Recently, G. Soto et al. produced amorphous magnesium-nitride films featuring different Mg:N ratios Si substrates in a nitrogen molecular atmosphere through Deposition using pulses of laser. These methods are limited in their industrial production due to their high costs, the lengthy process and complex operation of equipment or the low yield of magnesium nitride.
Although the direct reaction between magnesium powder with nitrogen has economic value, the production from magnesium nitride needs more heat and a longer reaction time. Also, the shape of the powder is insufficient and easy for agglomeration, 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 H2 decomposed may hinder the formation of MgO. Therefore, ammonia gas can be used as a nitrogen source. Chen Faqin et al. utilized liquid ammonia for nitrogen source for the preparation of magnesium nitride powder through direct nutriding of magnesium. The following conclusions can be drawn: From a thermodynamic analysis, liquid amonia could react with magnesium powder faster than nitrogen to produce magnesium nitride. magnesium nitride containing an extremely high purity and uniform particles can be prepared at 600 and an ammonia atmosphere for 1h, after which it is heated to 800degrees, with an ammonia flow rate of 500ml/min as well as an nitriding duration of 1h.
