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 electricity.
