Dissolution rate and recrystallization of sodium-molybdenum-phosphorus oxide glasses

Abstract

Phosphate glasses have been able to establish themselves and have received renewed interest from several research teams around the world. The interest shown in our laboratory contributes to the valorisation of Moroccan phosphates and brings added value to the latter by diversifying their field of application. The aim is to study the dissolution rate (DR), recrystallization, and then carry out a structure-properties correlation of these glasses. The increase in DR is rapid for the first additions of Na2O. Thereafter, there is little variation in DR for compositions relative to contents x=0.05-0.15. For higher levels of Na2O, dissolution again increases significantly. Analysis of the X-ray diffractograms of the crystalline glass associated with the composition shows the formation only of the NaMoPO6 phase.
