Abstract
The influence of 0–16 mol% Sb2O3substitution for P2O5on the properties of ZnO–P2O5glasses has been investigated. It was shown that Sb2O3could participate in the glass network and thermal stability of the glasses decreased with increasing Sb2O3content. Glass transition temperatureTg, softening temperatureTs, and water durability all decreased firstly (up to 6 mol% Sb2O3added) and then increased. Substitution of 12 mol% Sb2O3led to a 16°C decrease inTgand 30°C decrease inTs, and weight loss of the glass was only 0.42 mg/cm2, which is ∼11 times lower than that of the glass without Sb2O3after immersion in deionized water at 90°C for 1 day. The glass containing 12 mol% Sb2O3might be a substitute for Pb‐based glasses in some applications.
