Abstract

Submicron particles of potassium niobate KNbO3 were prepared by new colloid chemistry method. A rock-salt-type KF block in a layered perovskite, K2NbO3F, with a K2NiF4 type structure was selectively dissolved in water to produce niobate nanosheets at room temperature. The self-assembly between niobate nanosheets in a colloidal solution produce the nano powder of potassium niobate.
