A method for acceleration of the polarizing crystalline ferroelectric materials with tungsten bronze structure

摘要

Poling of ferroelectric tungsten bronze-like crystalline material in which the cation sites are substantially filled is expedited by electrolysis at temperatures in excess of the ferroelectric Curie temperature for periods of the order of one hour for bodies one centimeter in length. Electrolysis is carried out in an atmosphere which will yield positive ions such as H+ , D+ and Li+ which migrate through the body during processing.
