Popis:	Transparent (Pb, Ba, La)Nb2O6 ceramics were hot-pressed and the dielectric, piezoelectric, optical and electro-optic properties of grain-oriented samples were measured. Anisotropies of about 1.3:1 to 2:1 in the permittivity, coupling factor and electro-optic coefficient were found between the directions parallel and perpendicular to the hot-pressing direction. Hot-pressed samples with a porosity of less than 0.5% showed a transmission of about 60% at a wavelength of 0.8 µm (0.2 mm in thickness). It was found that (Pb, Ba, La)Nb2O6 ceramics have highly acitve electro-optic effects.
