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