ABSTRACT
In this chapter, the experimental techniques for measuring selected thermal properties of glass are explained; for example, glass transition temperature (Tg), crystallization temperature, melting temperature, and thermal expansion coef‡cient. Experimentally derived data for oxide, nonoxide, glass, and ceramic tellurite forms are compared with data calculated with different models. We examine the correlations between thermal properties and average values for cross-link density, and summarize stretching-force constants. Viscosity, fragility, and speci‡c-heat capacities are compared between tellurite glasses and super-cooled liquids at Tg . Processing, properties, and structures of tellurite glass-ceramic composites are also discussed. Data of thermal properties for new and recent types of tellurite glass are also collected.
