Overview of Magnesium nitride (Mg3N2)
Magnesium nitride (Mg3N2) is an inorganic compound composed of nitrogen and magnesium. The cubic molecular formula is Mg3N2 and the molecular weight is 100.9494. Pure Magnesium nitride is yellow-green powder at room temperature, but magnesium nitride containing a part of magnesium oxide impurities is off-white. Magnesium nitride is soluble in acid, slightly soluble in ethanol and ether, and is easily combined with water (H2O) to decompose. Therefore, it needs to be stored in a vacuum-sealed, waterproof, and moisture-proof.
 
How can you make Magnesium nitride?
To prepare magnesium nitride, the magnesium belt can be burned in nitrogen. The reaction equation is:
3Mg+N2=Mg3N2
 
Application of Magnesium Nitride
Magnesium nitride is an inorganic compound with a very wide range of applications. It can be used for:
1. Preparation of nitrides of other elements with high hardness, high thermal conductivity, corrosion resistance, wear-resistance, and high-temperature resistance;
2. Preparation of special ceramic materials;
3. Foaming agent for manufacturing special alloys;
4. Used to manufacture special glass;
5. Catalytic polymer cross-linking;
6. Recycling of nuclear waste;
7. Catalyst materials for synthetic diamond synthesis and cubic boron nitride;
8. Additives for high-strength steel smelting, etc.
9. Magnesium nitride Mg3N2. (vacuum packaging)
10. The use of Mg3N2 as an additive:
(1) Magnesium nitride (Mg3N2) replaces the desulfurized magnesium in the smelting of construction steel, which is beneficial to increase the density, strength, tensile strength, and endurance of the steel, and increase the content of "Vitriol" (Vitriol) in the material
(2) 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.
