Differential Scanning Calorimetric Analysis of Phase Transition in LCD Materials

D. S. Kushwaha, Jyotsna Sinha

Abstract: The phase transition has been described according to the current thermo-dynamical theories as a first order or second order, recorded on the Differential Scanning Calorimetry (DSC) traces as an anomalous change in the deferential power P, different from the normal P variation only due to the heat capacity of the material where height h of the peak as the distance between the heat capacity trace or baseline and the maximum P during the course of the phase transition is exposed. In case of a pure second order phase transition, this height is the different, between the heat capacities before and after the transition. In case of pure first order phase transition, this height is different, between the heat capacities before and after the transition.

Keywords: phase transition, transition peak, DSC scan, specific heat, transition energy
