Fluorochlorozirconate Glass Ceramics For Computed Radiography, Adam Wesley Evans

Masters Theses

Heat treating fluorochlorozirconate (FCZ) glasses nucleates nanocrystals in the glass matrix, resulting in a glass ceramic that has optical properties suitable for use as a medical imaging plate. As the temperature of heat treatment rises, the resulting FCZ glass-ceramic becomes increasingly more opaque as the size of the orthorhombic phase BaCl­₂[barium chloride] nanocrystals grow within the glass matrix. This opaqueness negatively affects imaging. The effect of adding Fe³⁺[iron] on the valence state of zirconium and overall glass quality was investigated.

Samples were synthesized and characterized with differential scanning calorimetry to determine the temperature of the orthorhombic …
