| Abstract: | Polar glass-ceramics in the BaO-TiO2-SiO2 have been prepared by crystallizing the glasses in a temperature gradient. The dielectric constant,pyroelectric coefficient, thickness extension vibration electromechanical coupling factor and their temperature dependence are investigated.The results show that these ceramics are expected to be an important piezoelectric and pyroelectric materials. |
