The lattice parameter of TaC–TaB2 balk prepared by mechano-chemical and spark plasma sintering (SPS) was investigated by the Nelson–Riley method. In this study, TaC–B4C powder was milled for 3, 6, 9, 12 hours and sintered by spark plasma sintering. The lattice parameter and C/Ta ratio of TaC–TaB2 was calculated by the Nelson–Riley method and the Storms relation. In this research, TaC–B4C powder was reacted and produced TaC–TaB2 composite. Phase formation and powder morphology during milling and sintering were examined using different analysis techniques including XRD and FE-SEM. The lattice parameter of the powders was increased by milling time and sintering temperature.
