Abstract

The structural relaxation kinetics in the glass transition region for xSb2O3·(100-x)B2O3 glasses were examined from viscosity and heat capacity measurements. The aim was to clarify the correlation between the relaxation kinetics and the Sb-O chemical bonding state. It was shown that the structural relaxation kinetics of the binary antimony borate glasses is affected by boron coordination numbers and the covalent bonding character of Sb-O bonds, and consequently these glasses are regarded as a highly strong glass-forming system in the fragile/strong classification concept.
