Abstract

The effect of Al₂O₃ substitution on the acid durability of a Li₂O-ZnO-SiO₂ glass and its glass-ceramic was investigated depending on the applied heat treatments, the type and concentrations of acid solutions, and leaching time. Satisfactory acid durability was obtained by using 6 wt.% Al₂O₃ for the glass and 11 wt.% for the glass-ceramic. The acid resistance of both glasses and glass-ceramics was found to be affected markedly by the presence of P₂O₅ or TiO₂ used as nucleating agent.
