Description of Magnesium Silicide Mg2Si Powder :

Magnesium Silicide is an organic compound made of silicon and magnesium. The chemical formula for this inorganic compound is Mg2Si, with a molecular weight of 76.71. Cubic crystal in cyan or light purple. The melting point at 1102°C is the relative density at 1.94.

Magnesium silicide does not dissolve in cold water but will decompose in hot. The silica can be spoiled by heating it to 1200°C under hydrogen flow. For the alkali solution, it is stable. Their decomposition can produce hydrogen and silane. Mg2Si, the durable compound in the MG-Si binary, has a high melt point and hardness. High-elastic modus properties make it a narrow-bandgap n-type semiconductor material. These are used to manufacture optoelectronic devices and energy devices. Mg2Si has an entire structure that belongs to the facial cube lattice. Its space group is FM3M, and its group number is 225. The lattice constant A = 0.6391 nm. The crystal structure shows that each Si atom is in (0, 0, 0, 0), which forms a facial cubic structure of a long A. The MG atom, located in the (0.25, 0.25, 0.25) location, is found at the center of the tetrahedron consisting of Si atoms. It forms an unfilial structure of the edge length (A / 2). Magnesium Silicide is a narrow-gap semiconductor. While the conductivity of the crystals is n-type, they can also be doped with Ag or Ga, Sn or Li (at a high doped level).

Production Method of  Silicide for Magnesium Mg2Si Powder:

Molten salt electrolysis method

Molten salt electrolysis is a standard method for preparing magnesium silicide. The molten salt system is formed with magnesium chloride or magnesium nitrate as raw material and the appropriate amount of sodium chloride or potassium chloride as flux. Electrolysis at high temperatures causes magnesium ions to precipitate on the cathode and silicon ions to pour on the anode to obtain magnesium silicide. The molten salt electrolysis method has high production efficiency and purity, but it requires high temperature and high-pressure equipment, and the purity of raw materials is more elevated.

Chemical synthesis

Chemical synthesis is also a method of preparing magnesium silicide. The technique takes magnesium chloride or magnesium nitrate as raw material, adding the appropriate amount of ammonia water or sodium hydroxide solution as a reactant so that magnesium and silicon ions react to form magnesium silicate precipitation. The chemical synthesis method has the advantages of mild reaction conditions and high purity of raw materials. Still, it needs to use a lot of chemical reagents, and the purity and particle size of the product need to be further improved.

Laser melting method

Laser melting is a new method for preparing magnesium silicide. In this method, magnesium powder and silicon powder are mixed, and the mixed powder is irradiated by a laser beam to reach a high-temperature melting state instantly. In the melting process, magnesium powder and silicon powder react to form magnesium silicide material. The laser melting method has the advantages of short preparation time, high purity, fine particle size, etc.. Still, it needs to use a high-power laser, and the particle size and purity of the raw material are required.
