Application scope and synthesis method of magnesium silicide Mg2Si powder

Overview of magnesium silicide Mg2Si powder

Magnesium silicide is an inorganic compound with the chemical formula Mg2Si. It 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 bandgap n-type semiconductor material. It has important application prospects in the fields of optoelectronic devices, energy devices, lasers, semiconductor manufacturing, constant temperature control communication and so on.

Magnesium silicide Mg2Si synthesis method

1. 2Mg+SiMg2Si is mixed according to the mass ratio of magnesium chips and silicon powder 3:1, placed in a MgO boat, heated to 450 ℃ in a high vacuum to start the reaction, the volume expands significantly, and the reaction is completed after a few minutes. Excessive magnesium exists in the obtained product, it can be broken and soaked in anhydrous ether, and magnesium can be dissolved out by treating with iodoethane (it can also be treated with bromobenzene ether solution and a small grain of iodine). Then, it was washed with diethyl ether, and after volatilizing the diethyl ether at room temperature, it was dried at 300° C. to obtain gray-blue glossy magnesium silicide crystals.

2. SiO2+4MgMg2Si+2MgO is heated with silicic acid for several hours to obtain SiO2. The SiO2 was finely ground and mixed with magnesium powder twice the mass of SiO2, then placed in an iron crucible, which was then immersed in cold water. The magnesium powder is ignited with an ignition agent, the reaction begins, and the dazzling white light quickly spreads over the whole crucible. Immediately cover the crucible cover with a gas conduit, and pass the H2 flow through the conduit. After the reaction is over, the crucible is gradually cooled down, and the product magnesium silicide is sintered into a hard block.

Application of magnesium silicide Mg2Si powder

Magnesium silicide is generally used in the production of aluminum alloys, which contains about 1.5% of magnesium silicide, and has an age-hardening function, which can form a GP zone and a very uniform precipitation phase, thereby increasing the strength of the alloy.

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

The main potential electronic application of MG2Si is thermoelectric generators.

Magnesium silicide is mainly used to synthesize other silicides.

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

Magnesium silicide is a by-product of the use of silicide.
