Effect of molybdenum addition on the thermal properties of silicate–phosphate glasses

Aim of the study was analysis of two groups of glasses: silicate–phosphate (41 mol.% SiO 2 –6 mol.% P 2 O 5 ) and with inverse phosphate–silicate matrix (41 mol.% P 2 O 5 –6 mol.% SiO 2 ) modified by the addition of molybdenum ions. Their effect on glass forming ability, glass transition effect, cry...

Zusammenfassung:	Aim of the study was analysis of two groups of glasses: silicate–phosphate (41 mol.% SiO 2 –6 mol.% P 2 O 5 ) and with inverse phosphate–silicate matrix (41 mol.% P 2 O 5 –6 mol.% SiO 2 ) modified by the addition of molybdenum ions. Their effect on glass forming ability, glass transition effect, crystallization process, and kind of crystallizing phases was examined using such methods as DSC, XRD, and SEM. It was found that the solubility limit of MoO 3 in silicate–phosphate glasses is 4.4
