How is magnesium silicide Mg2Si powder produced?

Magnesium silicide Mg2SiCharacteristics of powder

Magnesium silicide Mg2Si powder (CAS 22831-39-6) has high melting point, high corrosion resistance, high oxidation resistance, good electrical conductivity, high temperature ductility, and the intermediate phase of the binary alloy system.

How is magnesium silicide Mg2Si powder produced?

Silica powder with a particle size of 180, 100 grams of magnesium powder with a certain molar ratio, fully mixed into iron, put into a tubular reactor, evacuated and used a hydrogen reaction system 3 times, evacuated to 133 Pa, A In a closed reactor, the temperature is slowly raised to a certain temperature, and after a period of time, the reaction product is reduced to room temperature at a certain rate to obtain the reaction product. Through the research of magnesium silicide, the optimized process conditions are reaction temperature 600℃, reaction time 4h, mg:Si molar ratio 2.02:1, cooling rate 10℃/min, product quality, and more magnesium silicide content. More than 98%.

Overview of magnesium silicide Mg2Si powder

Magnesium silicide is insoluble in cold water and decomposes in hot water. It can be completely decomposed in a vacuum, or heated to 1200°C under a stream of hydrogen. Stable to alkaline solution. Decomposes and produces silane and hydrogen. Mg2Si is the only stable compound in the MG-Si binary system. It has the characteristics of high melting point, high hardness, and high elastic modulus. It is a narrow band gap n-type semiconductor material and can be used in optoelectronic devices, energy devices, lasers, semiconductors, and heavy metals. Fields such as temperature control communication have important application prospects. In the Mg2Si phase, the crystal has an overall structure, which belongs to the face cubic lattice, the space group is FM3M, the group number is 225, and the lattice constant a = 0.6391 nm. In the crystal structure, each Si atom is located at the (0, 0, 0) position, forming a face cubic structure with side length A. The MG atom is located at each position (0.25, 0.25, 0.25). The MG atom is located in the center of the tetrahedron composed of Si atoms, forming a monofilament structure with a side length of A/2. Magnesium silicide is a narrow gap semiconductor. The growth of the crystal exhibits n-type conductivity, but it can be doped by doping Ag, Ga, Sn and possibly Li (high doping level).

Application of magnesium silicide Mg2Si powder

Magnesium silicide is generally used to produce aluminum alloys, which contain about 1.5% of magnesium silicide, which has an age hardening function, can form GP regions and a very uniform precipitation phase, thereby improving the strength of the alloy.

Magnesium silicide is used to generate 6000 series aluminum alloys, in which the content of aluminum alloy is about 1.5%. The combined gold can be hardened to form Guinier-PRESTON zone and very fine precipitates, both of which will lead to an increase in the strength of the alloy.

The main potential electronic application of MG2Si is a thermoelectric generator.

Magnesium silicide is mainly used to synthesize other silicides.

Magnesium silicide is used to synthesize MgSin2 powder. It belongs to the method of preparing non-oxide ceramic powder.

Magnesium silicide is a by-product use of silicide.
