About Magnesium Silicide Mg2Si Powder:
Magnesium silicide is an inorganic compound composed of magnesium and silicon, and the chemical formula is Mg2Si, and the molecular weight is 76.71. Cyan or light purple powder, cubic crystal. The melting point is 1102 ° C, the relative density 1.94.
Magnesium silicide is insoluble in cold water and decomposes in hot water. It can be completely decomposed in vacuum or heating to 1200 ° C under hydrogen flow. Stable for the alkali solution. Decompose and produce silane and hydrogen. Mg2Si is the only stable compound of the MG-Si binary system, which has a high melting point, high hardness, high-elastic modulus characteristics, is a narrow bandgap n-type semiconductor material, manufactured in optoelectronic devices, energy devices, lasers, semiconductors, Heavy temperature control communication and other fields have important application prospects.  The Mg2Si crystal has an entire structure, which belongs to the facial cubic lattice, the space group is FM3M, the group number is 225, the lattice constant a = 0.6391 nm. In the crystal structure, each Si atom is located in the (0, 0, 0) position, forming a facial cubic structure having a side length A. The MG atom is located at a position (0.25, 0.25, 0.25) position, each MG atom located at the center of the tetrahedron composed of Si atoms, forming an unfilial structure of the edge length A / 2. Magnesium silicide is a narrow gap semiconductor. The growth of the crystals exhibits n-type conductivity, but it can be doped by doping with Ag, Ga, Sn, and possible Li (in high doped level). Feel free to send an inquiry to get the latest price if you would like to buy Magnesium Silicide Mg2Si Powder in bulk.

How is Magnesium Silicide Mg2Si Powder produced?
The silica powder having a particle diameter of 180, magnesium powder is 100 g in a certain molar ratio, mix well into the iron, put the tubular reactor, vacuum and use a hydrogen gas reactive reaction system 3 times, vacuum to 133 Pa, A closed reactor, slowly warming up to a certain temperature, and after a while, the reaction product is lowered to room temperature at a certain rate to obtain the reaction product. Through the research of the silicide magnesium, the optimized process conditions are reaction temperature 600 ° C, the reaction time 4 h, mg: Si molar ratio 2.02: 1, cooling rate 10 ° C / min, product quality, magnesium silicide content of More than 98%.

Application of Magnesium Silicide Mg2Si Powder:
Magnesium silicide is often used to produce aluminum alloys, which contains about 1.5% magnesium silicide, with aging hardening features, can form G.P area and very uniform precipitation phase, which can improve the strength of the alloy.
Magnesium silicide is used to generate a 6000 series of aluminum alloys containing up to about 1.5% Mg2Si. The alloy of the group can be hardened to form the Guinier-PRESTON zone and a very fine precipitate, both result in an increase in the strength of the alloy.
The main potential electronic application of MG2Si is a thermoelectric generator.
Magnesium silicide is primarily used to synthesize other silicides.
Magnesium silicide is used to synthesize MgSin2 powder. It belongs to the preparation of non-oxide ceramic powder.
A by-product use of silicide of magnesium silicide.
