Abstract Glasses composed of ternary components (35 – x)Sb 2 O 3 –xBi 2 O 3 –65P 2 O 5 (0 ⩽ x ⩽ 20 mol%) have been prepared and investigated as a potential alternative to lead-free glass for low temperature applications. Their structural properties were studied by Infrared Spectroscopy IR and Differential Thermal Analysis DTA. Results from the IR showed that Sb 3+ and Bi 3+ were responsible for glass network structure, which was supported by the diversification of density ρ and molar volume V m with an increasing amount of Bi 2 O 3 . Glass transition temperature T g , thermal stability, and coefficient of thermal expansion increased after substitution of Bi 2 O 3 for Sb 2 O 3 within the range of 0 mol% to 20 mol%. The water durability decreased and then increased; it could be attributed to the corrosion resistant P–O–Sb bonds. A typical sample of 25Sb 2 O 3 –10Bi 2 O 3 –65P 2 O 5 possesses excellent properties and can be a promising candidate for further applications.
