Crystallization of Sodium Borosilicate Glass with the Addition of Cr2O3
Glass composition of 6Na2O 22B2O3·70SiO2·2Cr2O3 is studied by scanning electron microscopy, X‑ray powder diffractometry (XRPD), and differential thermal analysis, depending on the duration of heat treatment at a temperature of 550°C. It is established that during heat treatment for 24–96 h, a phase separation structure with interpenetrating phases is formed in the studied glass, and a crystalline phase of eskolaite—Cr2O3 is also formed. With the maximum heat treatment duration of 96 h, cristobalite is formed in the bulk of the glass, which is accompanied by a decrease in the glass transition temperature of the low-viscosity phase. In this case, the intensity of eskolaite peaks decreases. Cr2O3 and SiO2 crystallize apparently due to the substance of the low-viscosity phase.
