Title: Physical and thermal properties of simulated nuclear waste glasses and their melts. Final report

Technical Report ·
OSTI ID:5266003

The physical and thermal properties of three simulated nuclear waste glasses (high iron, TDS and high alumina) and their melts were measured. The low temperature properties included: thermal diffusivity, thermal expansion, Young's modulus, modulus of rupture, Poisson's ratio, annealing point, glass transition temperature, dilatometric softening point, and specific heat. The high-temperature properties included: viscosity, density, and thermal diffusivity. The measurement of thermal diffusivity at low temperatures was based on a method described by Plummer. In this work, however, temperature-time data pairs were collected in a digital form and fed directly into a numerical analysis program. In this way, excellent agreement between measured and calculated values of thermal diffusivity was obtained for a standard glass, e.g., vitreous silica. High-temperature thermal diffusivity was measured by the method of Van Zee and Babcock. As in the low temperature diffusivity measurements, temperature-time data pairs were collected and analyzed numerically. The remaining properties were measured by normal methods. In most instances, data were first obtained on reference materials as a means of verifying experimental procedures and methods of analysis.
