Abstract

KNbO3 is a perovskite ferroelectric ceramic material with important electro optical and non linear optical properties. Its macroscopic properties depend on a number of inter-related features such as crystal structure, domain structure, defects and impurity content. KNbO3 has four known solid phases: cubic - tetragonal - orthorhombic - monoclinic. The paraelectric to ferroelectric transition occurs during the cubic to tetragonal transformation. The aim of this investigations is to study the orthorhombic to tetragonal phase transformations using KNbO3.
