The densification parameters have been calculated for CoSb3 nanopowders treated within the field activated sintering. We have obtained the values of creep activation energy, strain rate sensitivity exponent and material parameter that characterize the creep process. It is concluded that densification of CoSb3 is due to the grain boundary sliding based creep. The simulation of the sintering process has been carried out using the finite element method; the change of sample sizes due to densification has been calculated using the creep model. The conformity between simulation and experimental results has been shown.
