100.9494. CAS: 12057-71-5
EINECS: 235-022-1 Melting point: 800℃, boiling point: 700℃, greenish yellow powder 

or block, relative density is 2.712, 800℃ decomposition, 700℃ in vacuum sublimation, 

magnesium nitrided as an ionic compound, rapid hydrolysis in water. Soluble in acids, 

insoluble in ethanol, magnesium nitride, like many metal nitrides, reacts with water to 

produce ammonia.
Magnesium nitride is widely used. Magnesium nitride is an indispensable sintering 

assistant in the solid reaction of boron nitride and silicon nitride ceramics with high 

hardness, high thermal conductivity, wear resistance, corrosion resistance and high 

temperature resistance. Magnesium nitride plays an important role in the recovery 

of nuclear fuel, the purification of magnesium alloy melt and the catalysis of hBN reaction. 

In addition, Mg3N2 as an additive can effectively desulfurize and increase alum, so as 

to improve the density, strength, tensile force and bearing capacity of steel.
It has a wide range of applications; Magnesium nitride can be used as:
1. Prepare nitride of other elements with high hardness, high thermal conductivity, 

corrosion resistance, wear resistance and high temperature resistance;
2. Prepare special ceramic materials;
3. Foaming agent for making special alloy;
4. Used for making special glass;
5. Catalytic polymer crosslinking;
6. Recycling of nuclear waste;
7. Catalysts for synthetic diamond and cubic boron nitride;
8. Additives for high strength steel smelting, etc.
9. Magnesium nitride Mg3N2.(Vacuum package)
10. USES of Mg3N2 as an additive:

(1) nitride magnesium (Mg3N2) alternative construction in steel smelting magnesium 

desulfurization, favorable to improve the density of steel tensile strength and endurance, 

increase material internal alum (Vitriol) content, reached the standard of the Chinese 

government put forward the quality construction of steel (2) using magnesium nitride

 (Mg3N2) desulfurization, can reduce other additives, which helps to reduce the 

production cost of construction steel in our country is now in the products of steel 

factory, the average cost per ton lower RMB 300-450 yuan ($36.3-54.5) application:

1. Magnesium and magnesium alloy is the lightest metal structure material in engineering 

application, the deformation of the plastic forming technology of magnesium alloys in 

recent years has become the world's magnesium industry important research field of 

magnesium alloy in the future of the energy shortage will occupy more important position 

at present, magnesium alloy in aerospace automobile electronics building industry and 

daily life is indispensable important material but magnesium alloy in the widely used at 

the same time it still has its weakness, such as low hardness, strength, and melting point 

is lower than common metals such as steel how to improve the ability of plastic forming 

of magnesium alloy has become the research of magnesium alloysHot, therefore, seeking 

a good hardness, strength, but also has high specific strength and specific stiffness, has 

important academic and industrial application value (2) in recent years, along with the 

development of high-end its mechanical and electrical products production requirements, 

on the mechanical properties of magnesium alloy to need to further improve, with particulate 

reinforced magnesium matrix alloy material can exert magnesium alloy matrix at the same 

time and enhance the benefit of phase, significantly improve the strength of the magnesium 

alloy with elastic modulus of hardness and wear resistance and particulate reinforced 

magnesium matrix alloy material because of its low cost, strengthRigidity is high, in the 

field of modern industrial production, such as advanced manufacturing, have broad application 

prospects (3) based on the above purpose, using non-toxic pollution-free is added in the 

magnesium alloy magnesium - nitride nanotubes particles to enhance the strength of the 

magnesium alloy materials, good toughness and hardness, at the same time, to effectively 

improve conductive and heat conduction performance of magnesium alloy substrate material 

chemical composition and quality score is: magnesium Mg: 90-98, the remaining ingredients 

for aluminium Al for patent, to improve the performance of magnesium alloy in our country's 

existing magnesium alloy in the patent 200880017616.2, by adding indium scandiumYttrium 

and other precious metals and 2-3% of rare earth metals, smelting finished sample grain 

size less than or equal to 3 microns, the invention adds more precious metal elements 

content = high, high manufacturing costs in the patent 201210324168.9, select capable of 

improving the Mg alloy amorphous formation (Er, Cu, Ag) as alloying elements, selects the 

common casting and hot extrusion method preparation of the alloy material, and after casting 

and extrusion for magnesium alloy with the above alloys have the rare metal addition, although 

can improve ductility of magnesium alloy materialsHardness and abrasion resistance, but increased

the magnesium alloy smelting cost, at the same time, to achieve higher strength and abrasion 

resistance, need to be further in-depth study CN201610474622.7 proposes a processing process 

stable low-cost non-polluting emissions can be under the condition of conventional smelting 

production of magnesium - nitride carbon nanotubes preparation of particulate reinforced 

magnesium matrix alloy, magnesium alloy material with a more traditional strength toughness 

of hardness and wear resistance increased greatly, therefore, by adding magnesium - nitride 

carbon nanotubes particle reaction enhancement purpose to the mechanical properties of 

magnesium alloy materials.
