Effect of microwaves on the synthesis, structural and dielectric properties of Ca-modified BaTiO3 ceramics

A pre-heat treatment with a domestic microwave, (MW), performed on gel-dry of sol gel processed Ca-modified BaTiO 3 , with the chemical formulation Ba 1− x Ca x TiO 3 such as x  = 0, 1, 5, 10, 15, 20 and 30%, has been shown to lower the calcination temperature of these samples and to strongly influe...

Description
Summary:A pre-heat treatment with a domestic microwave, (MW), performed on gel-dry of sol gel processed Ca-modified BaTiO 3 , with the chemical formulation Ba 1− x Ca x TiO 3 such as x  = 0, 1, 5, 10, 15, 20 and 30%, has been shown to lower the calcination temperature of these samples and to strongly influence their physicochemical properties. Indeed, X-ray diffraction and Raman characterizations of the samples revealed a gradual change from tetragonal to pseudo cubic phase with increasing x and a predominance of the occupation of the Ti-site for the composition x
