What is Magnesium Nitride?

Magnesium nitride, is an inorganic compound with the chemical formula Mg3N2. It belongs to the cubic crystal system. At area temperature level, pure magnesium nitride is a yellow-green powder, however magnesium nitride having a section of magnesium oxide contaminations is grayish white.

The molar mass of magnesium nitride is 100.95 g/mol. Its density is 2.712 g/cm3. Magnesium nitride is totally liquified in acid and water, but partially dissolved in ether and also ethanol.

The melting factor of magnesium nitride is 1500 levels. Magnesium nitride, like numerous steel nitrides, reacts with water to create ammonia. Usually made use of as a driver. React with acid or liquid nonmetallic oxides to create ammonium salts and also magnesium salts.



Magnesium nitride is ceramic in nature. Magnesium nitride has high rust resistance and also greatly enhances manufacturing performance. Magnesium nitride likewise has high thermal conductivity, as well as high rust resistance and also temperature level resistance. Magnesium nitride has one more excellent significance since it is used as a driver for the synthesis of boron nitrogen.



What is Magnesium Nitride Used For?

1. Used as a catalyst when prepare the nitride of various other components with high firmness, high thermal conductivity, deterioration resistance, use resistance as well as heat resistance. In the initial successful synthesis of cubic boron nitride, the catalyst was magnesium nitride.

2. Made use of for high toughness steel smelting ingredients. Magnesium nitride (Mg3N2) replaces desulphurized magnesium in construction steel smelting, which is beneficial to boost the thickness, strength, tension as well as birthing force of steel. In addition, making use of magnesium nitride (Mg3N2) desulfurization, can decrease the quantity of other additives, therefore assisting to reduce the manufacturing expense of building steel;

3. Made use of to prepare unique ceramic materials;

4. For the manufacture of special alloy frothing representative;

5. For producing unique glass;

6. For catalytic polymer crosslinking;

7. For the recycling of nuclear waste;



How to Produce Magnesium Nitride?

Currently, the main prep work approaches of magnesium nitride include direct response technique of magnesium powder with nitrogen, response approach of magnesium with nitrogen in nitrogen plasma flow, magnesium coil surge method in nitrogen atmosphere, reduced pressure chemical gas corresponding item approach, self-propagating high temperature synthesis method, nano magnesium nitride synthesis method, etc.



Lately, G. Soto et al. ready amorphous magnesium nitride movies with various Mg ∶ N ratios on Si substratums in a molecular nitrogen environment by pulse laser deposition. These methods limit their commercial production due to high price, lengthy procedure, complicated equipment procedure, or low yield of magnesium nitride.



Although the straight reaction of magnesium powder with nitrogen has industrial value, the production of magnesium nitride powder needs greater reaction temperature as well as longer reaction time, and the shape of particles is insufficient and easy to agglomerate, which can not fulfill the demands of industrial top quality. NH3 can be decomposed into N- with busted bonds much more quickly than N2, and also the disintegrated H2 can prevent the development of MgO, so ammonia gas can be used as the nitrogen source. Chen Faqin et al. utilized fluid ammonia as nitrogen source to prepare magnesium nitride powder by straight nitriding of magnesium powder. The following conclusions might be drawn: Through thermodynamic analysis, liquid ammonia might respond with magnesium powder more conveniently than nitrogen to prepare magnesium nitride; High quality magnesium nitride powder with high purity and also uniform powder particles can be prepared at 600 ℃ as well as ammonia ambience for 1h, then heated up to 800 ℃, ammonia flow price of 500ml/min and also nitriding time of 1h.
