Abstract
Perovskite-type KNbOSUB3/SUB particles were prepared by hydrothermal process using mixture of niobium oxide and KOH solution.Obtained sample were characterized by using XRD and SEM. Single phase of orthorhombic KNbOSUB3/SUB were obtained under 150SUPo/SUPCin reaction temperature,over 48h in reaction time and over 3.2 mol/dmSUP3/SUP in KOH concentration.KNbOSUB/3SUB having rod like morphology was obtained under the condition over 6.4mol/dmSUP3/SUP in KOH concentration.It was found that morphology of KNbOSUB3/SUB depended on KOH concentration.
