Abstract

We have investigated the slow dynamics in the glass transition region of a supercooled liquid [Ca(NO3)2]0.4[KN3]0.6 by measuring the dynamic specific heat in the frequency range from 0.01 Hz to 5 kHz. The equilibrium dynamics of the system in this range is well described by the stretched exponential function, exp[-(t/τ)β], and the Vogel-Fulcher type relaxation time, τ = τ0exp[Δ/(T − T0)].

2. A supercooled liquid is said to be in equilibrium, even though the true ground state is crystalline below the freezing temperature. It is assumed that the escape time to the crystalline state is much longer than the internal equilibration time of the supercooled liquid and therefore one can disregard the crystalline state in the phase space and speak of the equilibrium liquid. This is presumably the case with supercooled CKN.Google Scholar
