What is Magnesium Nitride

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 temperatures of room temperature, the pure magnesium nutridide is a yellowish-green powder however magnesium nitride, which has some magnesium oxide particles is grayish white.

The Molar mass of magnesium-nitride is 100.95g/mol. This mineral's density is 2.712g/cm3. Magnesium nitride dissolves completely in acid and water, but is partially dissolvable when mixed with Ether and ethanol.

The melting temperature of magnesium nitride can be found at 1500 degrees. Magnesium Nitride, just like many metal nitrides, reacts with water and produces ammonia. A catalyst is often employed. React with acid and aqueous nonmetallic oxidants to form ammonium salts and magnesium salts.

Magnesium Nitride is a kind of ceramic nature. Magnesium nitride exhibits high corrosion resistance and significantly increases production efficiency. Magnesium has high thermal conductivity, as well in high corrosion resistance and temperature resistance. Magnesium nitride also has a great significance since it's used as a catalyst during the chemical synthesis of boron.

What Do You Use Magnesium Nitride For?

1. A catalyst used to you are preparing the nitride of other elements that have high hardness as well as high thermal conductivity. wear resistance, corrosion resistance, and extreme temperature resistance. The first successful process of synthesis of cubic bore nitride, an active catalyst came from magnesium nitride.

2. The product is designed for use as high strength steel Smelting additives. Magnesium nitride (Mg3N2) is a substitute for desulphurized magnesium in construction smelting. It is useful in increasing the density, strength tension, and bearing force of steel. In addition, using of magnesium nitride (Mg3N2) desulfurizationwill decrease the amount of other additivesand help reduce the production cost of construction steel;

3. Utilized to make special ceramic materials;

4. In the process of making a special alloy foaming agent

5. To make special glass

6. For catalytic crosslinking of polymers

7. To reuse nuclear waste;

How to Produce Magnesium Nitride?

At present, the principal methods for making magnesium nitride are direct reactions method of magnesium powder with nitrogen, method of reaction of magnesium with nitrogen inside nitrogen plasma flow as well as the method for the explosion of magnesium coils in nitrogen atmosphere, low pressure chemical gas in conjunction with the product method, self-propagating high temperature process for synthesis, nano magnesium nitride synthesis technique and many more.

Recently, G. Soto et al. created amorphous magnesium Nitride films that have different Mg:N ratios Si substrates in a molecular nitrogen environment using the use of pulse-laser deposition. These techniques limit the industrial production of these films due to high cost, long process complicated equipment operation or a lower yield of magnesium Nitride.

Although the direct reaction between magnesium powder with nitrogen holds economic value, the production of magnesium nitride-based powder requires higher temperatures for reaction and a longer reaction time, and the form of the particles isn't perfect and easy for agglomeration, which can not meet the requirements for industrial quality. It is possible to decompose NH3 into Nbreaking bonds more easily than N2, and H2 decomposed may block the formation of MgO, so ammonia gas is a suitable nitrogen source. Chen Faqin et al. used liquid ammonia to serve as nitrogen source to prepare magnesium nitride powder through direct nutriding of magnesium. The following conclusions can be drawn: By thermodynamic analysis, liquid ammonia is able to react with magnesium powder far more easily than nitrogen for the production of magnesium nitride. magnesium nitride that is high purity and uniform powder particles is made by heating it to 600 and ammonia in 1h, then heated to 800, ammonia flow rate 500ml/min and an nitriding duration of 1h.
