Structure and Properties of Glasses in the MgSO4-Na2B4O7-KPO3 System

摘要

A glass formation region has been established in the MgSO4-Na2B4O7-KPO3 system. This region is located in the borate-phosphate part of the concentration triangle and occupies -40% of the triangle area. Based on the spectral data obtained (nuclear magnetic resonance, IR and Raman spectroscopy), a model is proposed in terms of which the physicochemical properties (such as the linear thermal expansion coefficient, the softening temperature, and the glass transition temperature) of the samples are discussed.
