Phase formation and particle size of Zn₂Nb₃₄O₈₇ powders which were synthesized by a solid state reaction via a simple vibro-miling technique have been investigated as a function of calcination conditions, for the first time, by using a combination of X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) techniques. In general, the results shown that increase both purityand particle size of the desired Zn₂Nb₃₄O₈₇ powders. Moreover, It has been found that the optimization of calcination condition (900°C, 1 h, 20°C/min) can successfully lead to a single-phase of submicrometer-sized Zn₂Nb₃₄O₈₇ powders.
