About Manganese Silicide MnSi2 Powder:
Manganese silicide MnSi2 is an intermetallic compound, a silicide of Manganese. Manganese silicide is a transition metal silicide and a kind of refractory intermetallic compound. The nanomaterial of manganese disilicide (MnSi2) shows special electrical, optical, magnetic and thermoelectric properties, and even has potential application value in the field of catalysis. It is a non-stoichiometric compound, and the silicon defect is expressed as MnSi2-x.The crystal structure of many MnSi2-x compounds is similar to the chimney ladder and is called the Nowotny phase.

How is Manganese Silicide MnSi2 Powder produced?
2g(0.036mol) of manganese, 2g(0.071mol) of silicon and 10g(0.16mol) of copper were placed in small blocks in a 10 mlAl2O3 crucible in a quartz ampoule with an open end. After being emptied and fused, the ampoule was placed in a high-temperature furnace with carbon-silicon rods. The temperature was raised to 1200 ° C within 12 hours and then lowered to 500 ° C at 10 ° C/ChemicalBookH.Remove the ampoule, cool it, then insert it into a thick diameter rubber tube and break the ampoule so that the ingot can be safely removed. The copper-rich Cu-Mn-Si substrates were dissolved in 8mol/L nitric acid, and the octahedral crystals were left. The crystals were washed with water and dried to obtain the MnSi2 crystal with an edge length of 2mm.
Applications of Manganese Silicide MnSi2 Powder:
Due to its unique physical and chemical properties, manganese disilicide (MnSi2) has been successfully used in the fields of complementary metal-oxide-semiconductor components, thin-film coatings, bulk structural components, electrothermal elements, thermoelectric materials and photovoltaic materials.
The power factor of generating capacity is 2.4mW/K2m, which is equivalent to about 2 times the original, by using the manganese silicate thermoelectric conversion material. It is also expected to achieve the engine and industrial field of industrial furnace emissions of waste heat such as 300 ~ 700℃ of unused heat into electricity of high power thermoelectric generation module.
