Heat capacitiesCp of title glasses were measured for temperature ranging from 50 to 550°C. True linear temperature dependences were observed for all studied glasses at temperatures sufficiently lower than the glass transition temperature. The temperature-compositionalCp dependence was described by the linear model with only statistically significant coefficients retained. The parameters were estimated using the standard least squares procedure. The results obtained may be used for evaluation of viscosity values according to Adam and Gibbs theory.
