Abstract: (10603 Views)
Spontaneous opal glasses were synthesized by addition of ZrO2, P2O5 and TiO2 to a base glass composition of the system ZnO-B2O3-SiO2. The opacity of the samples was measured by UV-Visible spectrophotometry and their chemical resistance was determinedina harsh alkaline environment, according to ISO 695. Based on the microstructural analysis, while addition of P2O5 led to a liquid-liquid phase separation, addition of ZrO2 and TiO2 led topartially crystallized glasses. Furthermore, The ZrO2bearing glass, which opacified through crystallization of zirconia, willemite and gahnite, showed the best chemical resistance.
