The Technology and Structural Properties of Special Glass Modified (Ba0.6Pb0.4)TiO3 Ceramics
Abstract
The present paper widely describes the details of technology of (Ba0.6Pb0.4)TiO3 ceramics modified with PbO-B2O3-Al2O3-WO3 special glass, as well as the influence of admixture on the microstructure and crystal structure of basic material. The microstructure investigations reveal the significant increase of grain size and a decrease of pores participation in volume of modified samples, whereas the X-Ray Diffraction (XRD) measurements show a decrease of the volume of unit cell. The obtained results are discussed due to processes occurring during the sintering process at high temperature.
