title: Crystallization behavior of rare-earth doped fluorochlorozirconate glasses.
abstract: A series of fluorochlorozirconate (FCZ) glasses, each doped with a different rare-earth, was prepared and examined to determine thermal stability and activation energy,Ea, of the dopant dependent BaCl2crystallization. Non-isothermal differential scanning calorimetry (DSC) measurements were done to investigate the endothermic and exothermic reactions upon heat treatment of the glass samples. In comparison to the rare-earth free FCZ glass, significant changes in the Hruby constant,Hr, andEawere found due to the addition of a rare-earth and also between the individual dopants.
