摘要：
Variable amounts of sulphate anions were introduced in the standard BATY fluoroaluminate glass. Up to 3% BaSO4 was substituted for BaF2. Sulphate-free BATY glass shows neither weight loss nor water-induced IR absorption band after 72 h leaching at 88-degrees-C. In the same conditions, sulphate-doped samples are corroded and the leaching rate appears correlated to sulphate concentration. Doping BATY glass with aluminium oxide decreases its chemical durability even more dramatically.
