Abstract
Inorganic phosphate glasses find applications in several fields of materials sciences such as ionic conductors, photonic materials, hermetic seals, rare-earth-doped solid-state lasers and biomedical materials. The properties of zinc phosphate glasses prepared via acid-base reaction involving orthophosphoric acid and the corresponding metal chloride were studied. The process at low temperature allows control of glass transition, softening, melting temperatures and leads to further possibility to incorporate rare-earth ions and various organic dyes of interest to obtain transparent and functional organic-inorganic phosphate low-melting glasses with high chemical durability.
