Fabrication and Enhanced Thermoelectric Properties of ...
Alumina nanoparticledispersed bismuthantimonytellurium matrix (Al2O3/BST) composite powders were fabricated by using ball milling process of alumina nanoparticle about 10 nm and ptype bismuth telluride nanopowders prepared from the mechanochemical process (MCP). The fabricated Al2O3/BST composite powders were a few hundreds of nanometer in size, with a clear phase.
