Spark plasma sintering (SPS) synthesis of CoSb<sub>3</sub> and LaFe<sub>4</sub>Sb<sub>12</sub> 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 CoSb<sub>3</sub> and 141 GPa for LaFe<sub>4</sub>Sb<sub>12</sub> were deduced. SPS has been also applied to compact alkali metal and alkaline-earth metal iron antimonides with filled skutterudite structure.
