Abstract

ABSTRACT: Approximate glass-forming region of a P2 O5 –ZnO–Na2 O (PZN) ternary system was investigated and determined. The properties of the glasses with ZnO contents between 35 and 50 mol-% were further investigated. When ZnO of 40P2 O5 –40ZnO–20Na2 O glasses is replaced by 1–5 mol-% Fe2 O3, respectively, the density, T g and T f increase first and then decrease, and they showed the maximum value of about 4 mol-% Fe2 O3 replacement, while CTE and weight loss vary in opposite ways and showed the minimum value at about 4 mol-% Fe2 O3 replacement. Structural studies were carried out by X-ray diffraction, infrared spectroscopy and Raman spectroscopy. With the increase in Fe2 O3, the reduction of P=O bond is the main reason for the increase in water resistance of PZNF glass.
