Abstract
Disclosed is a zinc phosphate glass consisting essentially, expressed in terms of mole percent on the oxide basis, of 31-34% P O , 0-2% Al O , 5-11% Li O, 5-13% Na O, 3-7% K O, with Li O+Na O+K O being 10-28%, 20-45% ZnO, 0-10% CaO, 0-10% BaO, 0-10% SrO, with CaO+BaO+SrO being 3-12%, and 0-2% SiO , said glass exhibiting a stable glass transition temperature below 450° C., a working temperature below 500° C., and a water durability of no more than 5×10 g/cm /min after immersion in water at 95° C. for 24 hours. The low-temperature glass of the present invention is particularly useful for producing glass/polymer blends. Glass/polymer blends containing the glass of the present invention are also disclosed.
