Popis:	International audience; This study provides experimental data on the physical properties and the chemical durability of zinc-lead-iron phosphate glasses with the general composition (100-x) (50P2O5-15ZnO-35PbO)-xFe2O3. The physical properties show that the addition of Fe2O3 results in a high reticulation of the glass network in the composition range 0 £ x £ 10. As a consequence, a drastic improvement of the chemical durability was noticed and the dissolution mechanism was found to be controlled by a hydrolysis reaction with a non congruent dissolution.
