How to Produce Magnesium Nitride?
What is Magnesium Nitrode? Magnesium nutride Is an organic compound with the chemical composition Mg3N2. It can be found in the cubic crystal system. Magnesium nitride, at room temperature, is a yellowish green powder. But, magnesium nitride which contains some magnesium oxide impurities, is grayish.
Molar mass for magnesium nitride (100.95g/mol) is Its density measures 2.712g/cm3. Magnesium-nitride can dissolve completely in acids and water but is partially dissolvable by ether and alcohol.
Magnesium Nitride has a melting temperature of 1500°C. Magnesium Nitride, just like other metal nitrides reacts to water to create ammonia. Used as a catalyst. Use acidic or aqueous nonmetallic compounds to react and form magnesium salts.
Magnesium oxide is made from ceramic. Magnesium nutride has high resistance to corrosion, which greatly increases production efficiency. Magnesium-nitride has an excellent thermal conductivity as well as high temperature and corrosion resistance. Magnesium-nitride is an important catalyst in the synthesis of Boron nitrogen.
How is Magnesium Nitrode Useful?
1. This is used to create nitrides of elements such as high hardness, high thermal conductivity or wear resistance. Magnesium nitride was the catalyst in the first successful synthesise of cubic boron nutride.
2. This is used for the production of high strength steel smelting add-ons. Desulphurized magnesium is replaced by magnesium nitride, Mg3N2. Magnesium Nitride (Mg3N2) can be used to enhance the strength, density, tension, and bearing power of construction steel. Additionally, magnesium nitride's (Mg3N2) deulfurization can help reduce production costs of construction steel.
3. Special ceramic material preparation
4. To make special alloy foaming agents
5. To make special glass
6. Catalytic polymer Crosslinking
7. This is for the reuse of radioactive waste
How To Make Magnesium Nitride
Presently, there are several methods to prepare magnesium nitride. These include the direct reaction method for magnesium powder with Nitrogen, reaction method for magnesium with Nitrogen in plasma flow, magnesium coil blast method in nitrogen atmosphere and low pressure chemical gases complementary product method. Self-propagating high temperatures synthesis, nanomagnesium nitride, etc.
G. Soto et.al. Pulse laser deposition allowed for the preparation of films amorphous in magnesium nitride with different Mg/N rates on Si substrates. Because of their complexity and high costs, these methods are not suitable for industrial production.
While direct magnesium-nitrogen reaction has some industrial value, it is more difficult and requires longer reactions times and higher temperatures. The shape of the particles can also be imperfect and easily agglomerated, so the powder cannot meet industrial quality standards. N2- with broken bonds can decompose NH3 faster than N2, while H2 can hinder the formation of magnesium oxide, so ammonia can be used to provide nitrogen. Chen Faqin et al. Liquid ammonia was used as a nitrogen source for magnesium nitride. This can be done by directly nitriding the magnesium powder. We can draw the following conclusion: Thermodynamic analysis shows that liquid ammonia could react more with magnesium powder than nitrogen to make magnesium nitride. Magnesium nitride powder of high quality and uniform particles can be made by heating 600 in ammonia at 800 for an hour. After this, heat to 800 and 500 ml/min. Finally, nitride time of one hour.
