What is Magnesium Nitride?

Magnesium nitride, is a not natural substance with the chemical formula Mg3N2. It belongs to the cubic crystal system. At room temperature level, pure magnesium nitride is a yellow-green powder, but magnesium nitride including a portion 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 entirely dissolved in acid and also water, however partly dissolved in ether and ethanol.

The melting point of magnesium nitride is 1500 levels. Magnesium nitride, like several steel nitrides, reacts with water to generate ammonia. Usually used as a driver. Respond with acid or liquid nonmetallic oxides to create ammonium salts as well as magnesium salts.



Magnesium nitride is ceramic in nature. Magnesium nitride has high rust resistance and also greatly boosts manufacturing efficiency. Magnesium nitride likewise has high thermal conductivity, as well as high rust resistance and also temperature resistance. Magnesium nitride has one more terrific relevance because it is used as a catalyst for the synthesis of boron nitrogen.



What is Magnesium Nitride Used For?

1. Used as a catalyst when prepare the nitride of other aspects with high hardness, high thermal conductivity, deterioration resistance, wear resistance and high temperature resistance. In the first effective synthesis of cubic boron nitride, the catalyst was magnesium nitride.

2. Used for high toughness steel smelting ingredients. Magnesium nitride (Mg3N2) changes desulphurized magnesium in building and construction steel smelting, which is advantageous to enhance the density, toughness, stress and birthing force of steel. On top of that, the use of magnesium nitride (Mg3N2) desulfurization, can lower the amount of various other ingredients, hence aiding to minimize the production expense of construction steel;

3. Made use of to prepare special ceramic materials;

4. For the manufacture of unique alloy foaming agent;

5. For manufacturing unique glass;

6. For catalytic polymer crosslinking;

7. For the recycling of nuclear waste;



How to Produce Magnesium Nitride?

Currently, the major preparation techniques of magnesium nitride include straight response approach of magnesium powder with nitrogen, response technique of magnesium with nitrogen in nitrogen plasma circulation, magnesium coil surge technique in nitrogen environment, low pressure chemical gas corresponding item method, self-propagating high temperature synthesis technique, nano magnesium nitride synthesis method, etc.



Just Recently, G. Soto et al. ready amorphous magnesium nitride films with various Mg ∶ N proportions on Si substratums in a molecular nitrogen atmosphere by pulse laser deposition. These approaches limit their commercial manufacturing as a result of high price, long process, intricate devices operation, or low return of magnesium nitride.



Although the direct response of magnesium powder with nitrogen has industrial value, the production of magnesium nitride powder needs greater response temperature as well as longer reaction time, and also the shape of particles is incomplete and simple to agglomerate, which can not satisfy the demands of industrial quality. NH3 can be disintegrated into N- with busted bonds more easily than N2, and the decayed H2 can hinder the formation of MgO, so ammonia gas can be utilized as the nitrogen resource. Chen Faqin et al. utilized fluid ammonia as nitrogen source to prepare magnesium nitride powder by direct nitriding of magnesium powder. The adhering to conclusions could be drawn: Through thermodynamic evaluation, fluid ammonia might react with magnesium powder more easily than nitrogen to prepare magnesium nitride; High quality magnesium nitride powder with high pureness as well as uniform powder fragments can be prepared at 600 ℃ as well as ammonia ambience for 1h, then warmed to 800 ℃, ammonia flow rate of 500ml/min and nitriding time of 1h.
