Manganese silicide is a kind of transition metal silicide, which is a kind of refractory intermetallic compound. Due to its unique physical and chemical properties, it has been successfully applied in complementary metal oxide semiconductor devices, thin film coatings, bulk structure modules, electrothermal elements, thermoelectric materials and photovoltaic materials. The nano materials show special electrical, optical, magnetic and thermoelectric properties, and even have potential application value in the field of catalysis. Using manganese silicide as thermoelectric conversion material, the power factor of generating capacity is 2.4mw/k2m, which is about 2 times of the original. Using materials, it is expected to realize the high-power thermoelectric power generation module which can convert the unused heat energy of 300 ~ 700 ℃ from the engine and industrial furnace into electricity. However, traditional preparation methods such as metallurgical or physical methods can not meet the requirements of the preparation of transition metal silicide nanomaterials.
However, the manganese silicide prepared by Haixin has high alloying degree, pure metal process, high purity and low magazine content.Tohoku University of Japan announced on December 1, 2016 that the power factor representing the power generation index has reached 2.4mw/k2m, which is equivalent to about 2 times of the original power generation index by using manganese silicide thermoelectric conversion materials. Using materials, it is expected to realize the high-power thermoelectric power generation module which can convert the unused heat energy of 300 ~ 700 ℃ from the engine and industrial furnace into electricityHigh silicide manganese (mnsi1.7) is composed of abundant ele
