Abstract:

As conventional phosphate glasses have low chemical durability, their application was

limited. Thus, many efforts have been focused on increasing their chemical durability. New

applications are emerging recently as environmental materials. The aim of this work is to study the

effect of calcium substitution by magnesium on thermal properties and the chemical durability of

the 3P2O5-2K2O-(1-x) CaO-xMgO glass system (0 ≤ x ≤ 1) in order to their application as a

vitrifiable controlled release fertilizer.

Keywords:

Phosphate, vitrifiable fertilizers, chemical durability, environment.
