Potassium niobate (KNbO₃) is an inorganic compound with the formula KNbO₃. A colorless solid, it is classified as a perovskite ferroelectric material. It exhibits nonlinear optical properties, and is a component of some lasers. Nanowires of potassium niobate have been used to produce tunable coherent light.
