Abstract

Mechanochemical synthesis of K_xNa_1-xNbO₃ powders, where x was from 0.1 to 0.9, has been investigated. A novel starting material of Nb(OH)₅ with higher reactivity than Nb₂O ₅ was prepared via wet chemical method. When x = 0.1, the pure perovskite phase was detected. With x increasing, the second phase of K ₂Nb₈O₂₁ was detected. When x = 0.5, perovskite phase were formed after milling 5h. For purposes of comparison, the starting material of Nb₂O₅ was also used to synthesize K _0.5Na_0.5 NbO₃ powders. The morphology of particles was studied by transmission electron microscopy (TEM).
