Crystallization during processing of nuclear waste glass

Under typical glass-processing conditions, crystals nucleate, grow, and dissolve in a nonuniform temperature field in a melt subjected to deformation and flow. Using examples of the results obtained on nuclear waste glasses, this paper describes various phenomena associated with crystallization under non-static conditions, such as crystal formation during batch melting, crystal settling at the melter bottom, and crystal precipitation during glass cooling, including its impact on glass corrosion resistance.
