Dielectric and optical properties of transparent ferroelectric glass-ceramic systems

Abstract The properties and behavior of optically transparent materials prepared by controlled crystallization of a ferroelectric phase from a glass are discussed. The dielectric and optical properties are different from those of the bulk materials and are shown to be a function of the crystallite size. The control of the crystallite size to values below 0.2 μm allows one to prepare transparent specimens which exhibit a large electrooptic effect. The dielectric and electrooptic properties are shown for a representative number of glass-ceramic systems.
