Preparation and properties of B-BaB2O4 glass ceramics

摘要

$beta@-BaB$-2$/O$-4$/ is a remarkable non-linear optical material for its large second harmonic generation coefficients and wide transparent range. Glass ceramics as a kind of functional materials was recently paid more attention because large size products can be more easily obtained and their properties can be compared with those of corresponding single crystals. In this paper $beta@-BaB$- 2$/O$-4$/ glass ceramics was prepared by melting BaCO$-3$/ and H$-3$/BO$-3$/ and following heat treatment the bulk samples. DTA, XRD and FTIR were used to investigate the phase separation and crystallization process of $beta@-BaB$- 2$/O$-4$/ second harmonic generation of glass $beta@-BaB$- 2$/O$-4$/ glass ceramics were studied.
