The glass transition and dynamic heat capacity of a glass-forming ionic liquid [Ca(NO3)(2)](0.4)[KNO3](0.6)

Abstract

The linear and nonlinear enthalpy relaxation of a supercooled liquid [Ca(NO3)(2)](0.4) [KNO3](0.6) in the glass transition region was investigated using the calorimetric methods such as modulation and adiabatic ones. It is demonstrated that the nonlinear enthalpy relaxation of [Ca(NO3)(2)](0.4) [KNO3](0.6) in the glass transition region is fully accountable in terms of the equilibrium response function if the latter is properly extended.
