Microstructure and phase transformation in KNbO₃

Research output: Contribution to journal › Article › peer-review

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.
