Abstract
The borophosphate glasses compositions based on (64-x)P2O5-5B2O3-15ZnO-15Li2O-15KF-1Sm2O3 are prepared by melting and quenched technique. All ingredients are mixed homogeneously in a porcelain crucible and the melting process uses a furnace with a temperature of 1200 C for 3 hours. Followed by an annealing process for 3 hours at a temperature of 500 C. Glass that is not cracked and has good transparency will then be cut and polish. The structure properties were obtained from X-Ray Diffraction (XRD) and Fourier Transform Infra Red (FTIR). The result of XRD spectra show that glass is an amorphous and FTIR spectra show that glass has symmetrical stretching of the P-O-B.
