Heating rate and composition dependence of the glass transition temperature of a ternary chalcogenide glass

Glass Transition Phenomena, Crystallization Kinetics and Enthalpy Released in Binary Se100-xInx (x = 2, 4 and 10) Semiconducting Glasses

“…3. This variation takes the form of a power law behaviour and may be represented by the following expression [14]:…”

“…Theoretically, T g is defined as the temperature at which the relaxation time t becomes equal to the experimental time of observation t obs . At the same time, T g varies inversely [14] as the relaxation time. With increasing heating rate, t obs decreases and hence the glass transition temperature increases.…”

“…where Z denotes the average coordination number [14] per atom and is calculated in terms of covalent bonding. This equation is similar to the empirical relation proposed by Tanaka [18] with the remarkable difference that the constant a in our case is negative showing a decrease of T g with Z.…”

Kinetics of Se75S25−xCdx glassy system using differential scanning calorimeter

“…(1) gives an excellent description of the dependence of T g , which increases with increasing heating rate, and the maximum deviation in the theoretical and experimentally measured values is within the average standard error. The heating rate dependence of glass transition temperature T g is an experimentally observed [20,21] fact. Theoretically, T g is defined as the temperature at which the relax-…”

“…Equation (1) gives an excellent description of the dependence of T g , which increases with increasing heating rate, and the maximum deviation in the theoretical and experimentally measured values is within the average standard error. The heating rate dependence of glass transition temperature T g is an experimentally observed [48,49] fact.…”
