What is Magnesium-Nitride?

Magnesium nitride is an inorganic compound with the chemical formula Mg3N2. It's particulate matter that is part of the Cubic Crystal System. At ambient temperature, magnesium nitride is a yellow-green powder however, magnesium nitride that contains a portion of magnesium oxide impurities can be grayish white.

The Molar mass of magnesium nutride is 100.95g/mol. The density of the mineral is 2.712g/cm3. Magnesium Nitride is totally dissolved in acid and water, but partially dissolved in the ethanol and ether.

The melting point for magnesium nitride is 1500 °. Magnesium nitride, like many metal nitrides reacts with water to form ammonia. Commonly used as a catalyst. React with acid , or aqueous nonmetallic oxides that result in ammonium salts as well as magnesium salts.

Magnesium nitride , a type of ceramic, is found in nature. Magnesium has excellent corrosion resistance and significantly increases the efficiency of production. Magnesium is also a great material for thermal conductivity as well in high corrosion resistance and temperature resistance. Magnesium is also of great significance because it serves as a catalyst to aid in the formation of boron.

What is Magnesium nitride Used for?

1. A catalyst used to make the nitride out of other elements with high hardness along with high thermal conductivity wear resistance, corrosion resistance, and extreme temperature resistance. The first successful formula for cubic boron, an active catalyst came from magnesium nitride.

2. Used for high strength steel additions to smelting. Magnesium Nitride (Mg3N2) is a substitute for magnesium desulphurized in construction steel melting, which helps to increase the density, strength tension, and bearing strength of steel. In addition, the process of magnesium nitride (Mg3N2) desulfurization, may reduce the quantity of other additives, helping to reduce the production cost of construction steel.

3. This is used to make special ceramic materials;

4. To manufacture a special alloy foaming agent

5. Special glass for manufacturing;

6. For catalytic crosslinking of polymers

7. For the recycling of nuclear waste

How Do You Produce Magnesium Nitride?

Presently, the most popular preparation methods of magnesium nitride are direct reactions method for magnesium powder using nitrogen, reaction method of carbon with nitrogen in nitrogen plasma flow methods for magnesium coils in nitrogen atmosphere Low pressure chemical gas complementing product method, self-propagating high temperature process for synthesis, nano magnesium Nitride synthesis method, and so on.

Recently, G. Soto et al. prepared amorphous magnesium nitride films featuring different Mg:N ratios Si substrates in a molecular nitrogen environment using an application of pulsed lasers. These methods hinder their production in the industrial sector due to the cost of production, lengthy process or complex equipment operation or low yields of magnesium nitride.

While the direct reaction of magnesium powder with nitrogen is of significant industrial potential, the making of magnesium powder requires more reaction temperatures and a longer response time. In addition, the shape of the particles are not ideal and easy to agglomerate that's why they don't meet the needs of industrial grade. N3 can be broken into Nand N2 - with broken bonds faster than N2 and the decomposed H2 could prevent the formation MgO, which is why ammonia gas could be used as the nitrogen source. Chen Faqin et al. used ammonia liquid as a nitrogen source to prepare magnesium nitride via direct the nitriding process of magnesium powder. The following conclusions could be drawn: Using thermodynamic analysis, liquid ammonia can react with magnesium powder faster than nitrogen in the preparation of magnesium nitride. Premium magnesium nitride powder that has excellent purity and uniform particles can be made at 600 and ammonia in 1 hour, and then heated to 800degrees, with an ammonia flow rate of 500ml/min with Nitriding time of 1h.
