A novel synthesis route for the fabrication
of p-type nanostructured skutterudite, FexCo1-xSb3
in large quantity is reported. This scalable synthesis route
provides nano-engineered material with less impact on
the environment compared to conventional synthesis
procedures. Several Fe substituted compositions have
been synthesized to confirm the feasibility of the process.
The process consists of a nano-sized precursor fabrication
of iron and cobalt oxalate, and antimony oxides
by chemical co-precipitation. Further thermochemical
processes result in the formation of iron substituted
skutterudites. The nanopowders are compacted by Spark
Plasma Sintering (SPS) technique in order to maintain
nanostructure. Detailed physicochemical as well as
thermoelectric transport properties are evaluated. Results
reveal strongly reduced thermal conductivity values
compared to conventionally prepared counterparts, due
to nanostructuring. P-type characteristic was observed
from the Seebeck measurements while electrical
conductivity is high and shows metallic behavior.
The highest TE figure of merit of 0.25 at 800 K has been
achieved, which is strongly enhanced with respect to the
mother compound CoSb3. This suggests the promise of
the utilized method of fabrication and processing for TE
applications with improved performance.
