Popis:	Spark plasma sintering (SPS) synthesis of CoSb3 and LaFe4Sb12 from ball-milled elemental metal powders has been performed obtaining samples with high relative densities (� 99%). Fracture behaviour, the microstructure and mechanical properties were studied. From ultrasound and nano-indentation measurements, Young’s moduli of 148 GPa for CoSb3 and 141 GPa for LaFe4Sb12 were deduced. SPS has been also applied to compact alkali metal and alkaline-earth metal iron antimonides with filled skutterudite structure. r 2007 NIMS and Elsevier Ltd. All rights reserved.
