Abstract EN
The world energy crisis had increased the demand for alternative energy sources and as such is one of the topics at the forefront of research.
One way for reducing energy consumption is by thermoelectricity.
Thermoelectric effects enable direct conversion of thermal into electrical energy.
Higher manganese silicide (HMS, MnSi1.75) is one of the promising materials for applications in the field of thermoelectricity.
The abundance and low cost of the elements, combined with good thermoelectric properties and high mechanical and chemical stability at high temperatures, make it very attractive for thermoelectric applications.
Recent studies have shown that Si-rich HMS has improved thermoelectric properties.
The most interesting of which is the unusual reduction in thermal conductivity.
In the current research, transmission (TEM) and scanning (SEM) electron microscopy as well as X-ray diffraction methods were applied for investigation of the govern mechanisms resulting in very low thermal conductivity values of an Si-rich HMS composition, following arc melting and hot-pressing procedures.
In this paper, it is shown that there is a presence of sub-micron dislocations walls, stacking faults, and silicon and HMS precipitates inside each other apparent in the matrix, following a high temperature (0.9 Tm) hot pressing for an hour.
These are not just responsible for the low thermal conductivity values observed but also indicate the ability to create complicate nano-structures that will last during the production process and possibly during the application.
