Ferroelectric properties of tungsten bronze ceramics

Abstract

Abstract Modified strontium barium niobate and lead potassium niobate ceramics with tungsten bronze structure were prepared by the conventional ceramic techniques. The effect of various dopants on the properties of strontium barium niobate ceramics have been investigated. Curie temperature decreases with the increase of the ionic radius of dopant. The properties of filled and unfilled structures are compared. The effect of La3+ on Lead Potassium Niobate is discussed.
