General description
Potassium niobate (KNbO3, KN) is a perovskite-type well-known ferroelectric material with a wide range of applications in electromechanical, nonlinear optical, frequency doubler, and holographic storage system applications. Single crystal of a KNbO3 is known to have high piezoelectric activity because of its high electromechanical coupling factors. Therefore KN materials have received much interest in the development of lead-free piezoelectric materials.
Application
Potassium niobate can be used to prepare bismuth sodium titanate(BNT)-KN ceramics (BNT–KN ceramics) by the mixed oxide method. The addition of KN to the BNT system increases the dielectric and piezoelectric properties of the BNT-KN ceramics. These properties of the ceramic system are suitable for the development of lead-free capacitors. Cu dopped KNbO3 single crystals also found application in semiconductor laser technology because Cu doping resulted in electronic states with near-infrared absorption bands.

(K(x),Na(1-x))NbO(3) (KNN) thin films were deposited on (001)SrRuO(3)/(001)Pt/(001)MgO substrates by RF-magnetron sputtering, and their piezoelectric properties were investigated. The x-ray diffraction measurements indicated that the KNN thin films were epitaxially grown with the c-axis orientation in the perovskite tetragonal system.

We have synthesized and characterized three types of perovskite alkaline niobate nanowires: NaNbO(3), KNbO(3), and LiNbO(3) (XNbO(3)). All three types of nanowires exhibit strong nonlinear response. Confocal imaging has been employed to quantitatively compare the efficiency of synthesized nanowires to

The piezoelectric properties and cytotoxicity of a porous lead-free piezoelectric ceramic for use as a direct bone substitute were investigated. Cold isostatic pressing (CIP) was applied to fabricate porous lithium sodium potassium niobate (Li0.06Na0.5K0.44) NbO3 specimens using a pore-forming method.
