Magnesium Nitride Mg3N2 Powder magnesium nitride formula CAS 12057-71-5

What is Magnesium Nitride? 

Magnesium nitride is an inorganic compound of magnesium and nitrogen. At room temperature and pressure, it is a green-yellow powder. Magnesium nitride is an inorganic compound composed of nitrogen and magnesium, with a molecular formula of Mg3N2 and a molecular weight of 100.9494. Belongs to the cubic crystal system. Like many metal nitrides, Magnesium nitride reacts with water to produce ammonia. To prepare magnesium nitride, the magnesium belt can be burned in nitrogen. It is often used as a catalyst.

Mg has two valence electrons and loses these two valence electrons to form the Mg2+ ion. It gains three valence electrons to form N3− ion. To balance charges, 3 Mg2+ ions combine with two N3− ions to form Mg3N2.

Magnesium nitride is soluble in acid and slightly soluble in ethanol and ether. Like many metal nitrides, Magnesium nitride reacts with water to produce ammonia. Reacts with acids or water-containing non-metal oxides to produce ammonium and magnesium salts. Because magnesium nitride is easily combined with water (H2O) to decompose, it must be stored in a vacuum-sealed, waterproof, and moisture-proof. TRUNNANO is a trusted global Magnesium Nitride supplier. Feel free to inquire about the latest Mg3N2 powder price of Magnesium Nitride anytime. Magnesium nitride is slightly harmful to water bodies. Do not expose undiluted or large amounts of products to groundwater, waterways, or sewage systems, and do not discharge materials into the surrounding environment without permission.

Like many metal nitrides, magnesium nitride reacts with water to generate magnesium hydroxide and ammonia gas.

Mg3N2(s)+ 6 H2O(l)→3 Mg(OH)2(aq)+ 2 NH3(g)

When magnesium is burned in the air, some magnesium nitride will be formed in addition to the main product, magnesium oxide.

The thermal decomposition of magnesium nitride produces magnesium and nitrogen (at 700-1500°C). How is Mg3N2 formed? Mg has two valence electrons and loses these two valence electrons to form the Mg2+ ion. It gains three valence electrons to form an N3− ion. To balance charges, 3 Mg2+ ions combine with two N3− ions to form Mg3N2.

Product Performance of Magnesium Nitride Mg3N2 powder:

Magnesium nitride has a wide direct bandgap, strong atomic bonds, high thermal conductivity, good chemical stability

(almost no acid corrosion) and other properties and strong anti-radiation ability in optoelectronics, high temperature, and

high power devices and high-frequency microwave device applications have a broad prospect.

How is Magnesium Nitride Mg3N2 Powder produced?

To prepare magnesium nitride, the magnesium belt can be burned in nitrogen.

What do magnesium and nitrogen make? Solid magnesium reacts with nitrogen gas to form solid magnesium nitride.

In the above reaction, if the nitrogen is not pure, producing products containing magnesium oxide is easy. The method of reaction in dry NH3 gas is better.

Place the magnesium scraps in a porcelain boat or a sintered magnesia boat. The boat is installed in a porcelain tube. One end of the porcelain tube is connected to a T-shaped tube. One end of the T-shaped tube can be filled with dry ammonia gas, and the other can be filled with nitrogen. The end of the porcelain tube is connected to a U-shaped tube, and the tube is filled with desiccant, half of which is small flakes of CaO, and the other half is small flakes of KOH. The gas discharged from the reaction tube is absorbed by the absorption device, which is two conical flasks containing dilute sulfuric acid. To prevent back suction, do not insert the tube of the first absorption bottle below the surface of the dilute sulfuric acid.

Pour dry NH3 and N2 into the porcelain tube until the second absorption bottle no longer emits bubbles, indicating the air in the porcelain tube has been purged. Raise the temperature to 800～850℃. Heat the magnesium powder for 4 hours; the magnesium powder becomes hot, marking the beginning of the reaction, and at the same time, H2 must be produced. During the reaction, the pressure of NH3 should be greater than the outside atmospheric pressure to avoid sucking back. When the reaction is over, turn off NH3, keep the original temperature, and continue to pass N2 for 1.5h to remove NH3·Mg3N2 adsorbed on Mg3N2, which is very delicious and must be stored in a dry container. If the magnesium belt is burned in the air, some magnesium nitride will also be produced in addition to magnesium oxide.

Applications of Magnesium Nitride Mg3N2 Powder:

Magnesium nitride (Mg3N2) powder is a well-known solid catalyst. It is an additive in various applications, including fabricating special alloys and ceramics, catalyzing polymer cross-linking reactions, and hydrogen storage materials. 

What is magnesium nitride used for?

1. Magnesium nitride is used as a catalyst when preparing nitrides of other elements with high hardness, high thermal conductivity, corrosion resistance, wear resistance, and high temperature resistance. When the cubic boron nitride was successfully synthesized for the first time, the catalyst used was magnesium nitride;

2. Magnesium nitride additives used in high-strength steel smelting. Magnesium nitride (Mg3N2) replaces desulfurized magnesium in construction steel smelting, which improves the density, strength, tensile strength, and endurance of steel. In addition, the use of magnesium nitride (Mg3N2) for desulfurization can reduce other additives in an appropriate amount, thereby helping to reduce the production cost of construction steel;

3. Preparation of special ceramic materials;

4. Foaming agent for manufacturing special alloys;

5. Magnesium nitride is used to manufacture special glass;

6. Catalytic polymer cross-linking;

7. Recycling of nuclear waste;

8. Magnesium nitride is a catalyst for synthetic diamond synthesis and cubic boron nitride.
