| Abstract Scope |
Solid state reaction is a simple method for preparing intermetallic thermoelectric, but typically takes too long to produce single phase microstructure and it hardly leads to fully dense product. A considerable amount of energy is needed for the preparation of a sample in the method. By increasing the starting materials interface and decreasing the diffusion distance, it is possible to reduce the time and temperature needed for preparing full dense product. This can be performed by ball milling of brittle-ductile material which can leads to preparation of ductile nano particles and-or highly activates them significantly facilitates the exothermic reactions.
In this work, we show that single-phase Al-Bi-doped Mg2-xAlxSi1-xBix components with superior thermoelectric properties can be successfully synthesized in a rapid single batch process at low temperature by activated reactive consolidation method. |
