摘要：

Both surface and bulk textures penetrating the whole volume of the glass may be formed in glasses of the La2O3-B2O3-GeO2 system near the stoichiometry of LaBGeO5 stillwellite. These textures cause non-linear optic, ferroelectric and pyroelectric properties of crystallized glasses. The present work represents SEM study of surface and bulk grain-oriented crystallization of stillwellite glasses for different conditions of synthesis of both planar surface (non-linear optic) and bulk (ferro/pyroclectric) textures based on oriented needle-shaped crystals of LaBGeO5 stillwellite.
