Elastic, Piezoelectric, Acousto-Optic and Electro-Optic Properties of Li2B4O7

Abstract
Transparent, core-free and good quality single crystals of Li2B4O7 have been successfully grown by the Czochralski method. All dielectric, elastic and piezoelectric constants, and their first- and second-order temperature coefficients have been determined by measuring resonant and antiresonant frequencies of bars and plates with various orientations. The theoretical and experimental results show the potential usefulness of Li2B4O7 for bulk wave or SAW applications. Further, measurements on optical, acousto-optic and electro-optic properties of Li2B4O7 have also been carried out.
