Synthesis and corrosion study of borophosphate glasses

Borophosphate glasses of composition 30Na2O - (60-y) B203 - yP205 -10 Al203 were prepared with the help of melt quench technique and studied the effect of corrosion on it. Polished samples of the borophosphate glass of various compositions were used for experiment. The glasses were characterized using XRD for their structural study. The polished samples of the borophosphate glass samples of various compositions 30NaO - (60-y) B2O3 - yP2O5 – 10 Al2O3 were exposed to 10% HCI and 10% NaOH separately at room temperatures for 24, 48 and 72 hrs. The effect of glass composition and the environment (acidic or alkaline) on the degradation behavior of these glasses was studied and interpreted. Weight loss was observed accordingly.
