What is Magnesium Nitride?
Magnesium Nitride is an inorganic compound with the chemical formula Mg3N2. It's part the cluster of cubic crystals. At room temperature, pure magnesium nutridide is a bright yellow-green color with parts of magnesium oxide impurities is grayish white.
The magnesium nitride's molar mass is 100.95g/mol. The density of the mineral is 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 lies at 1500 degrees. Magnesium, like other metal nitrides water to create ammonia. It is often used as a catalyst. React with acid or nonmetallic oxides , forming ammonium salts as well as magnesium salts.
Magnesium Nitride is a natural ceramic nature. Magnesium-nitride has superior corrosion resistance and greatly improves production efficiency. Magnesium nitride has also high thermal conductivity, aswell with high corrosion resistance and temperature resistance. Magnesium Nitride has an additional importance because it is used as a catalyst synthesizing of boron.
What is Magnesium nitride Used for?
1. This is used as a catalyst creating the nitride elements that have high hardness as well as high thermal conductivity. wear resistance, corrosion resistance, and extremely high resistance to temperature. The first successful chemical synthesis of cubic-boron nitride the catalyst was magnesium nitride.
2. Useful for high strength steel alloys for smelting. Magnesium nitride (Mg3N2) replaces the magnesium that has been desulphurized for construction melts, which is helpful to increase 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 reduce the amount of ingredients, and thus help to decrease the cost of production of construction steel;
3. Used to prepare special ceramic materials;
4. For the manufacturing of a specific alloy foaming agent;
5. For manufacturing special glass;
6. To crosslink catalytically-linked polymers.
7. To recycle nuclear waste
How do I Make Magnesium Nitride?
The main preparation methods of magnesium nitride comprises direct reaction method of magnesium powder with nitrogen, the method for resolving magnesium with nitrogen using nitrogen plasma flow using a magnesium coil blast method in nitrogen atmosphere Chemical gas at low pressure process, self-propagating high temperature method for synthesis, the synthesis of nano magnesium and many more.
Recently, G. Soto et al. made amorphous magnesium oxide films with different Mg:N ratios Si substrates within a molecular-nitrogen environment by pulse laser deposition. These methods hinder their industrial application due to the cost of production, lengthy process or complex equipment operation or low yield of magnesium nitride.
While the direct reaction of magnesium powder with nitrogen is of economic value, the production of magnesium nitride powder requires greater reaction temperatures and a longer reaction time. Additionally, the shape of particles is incomplete and easy to aggregate, and therefore, does not meet the requirements of industrial quality. In the process of decomposition, NH3 can form Nwhich has broken bonds more easily than N2, and the decomposed H2 will inhibit the formation of MgO, so ammonia gas is a suitable nitrogen source. Chen Faqin et al. utilized liquid ammonia for nitrogen source for the preparation of magnesium nitride using direct nitriding of magnesium powder. The following conclusions could be drawn from thermodynamic analysis, liquid amonia could react to magnesium powder more efficiently than nitrogen and produce magnesium nitride. Good quality magnesium nitride that is excellent purity and uniform particles can be made by heating them to 600, and then ammonia for 1 h, then heated up to 800°C, with an ammonia flow rate of 500ml/min with the nitriding process takes 1 hour.
