Microwave synthesis of KNbO₃ nanocubes

Abstract

Potassium niobate (KNbO₃) nanocubes were obtained by microwave synthesis. The synthesis was performed using niobium oxide (Nb₂O₅) and potassium hydroxide (KOH) as starting materials. Water was used as the reaction medium. KNbO₃ particles with perovskite structure were confirmed from X-ray diffraction (XRD). The morphology of the KNbO₃ was investigated using transmission electron microscopy (TEM). KNbO₃ nanocubes were synthesized by microwave synthesis at low temperature.
