and increases with a similar gradient to the reference as before. The difference (∆T)<br />

between curves TR and Ts are plotted in fig. (4.1c) which forms the DTA trace.<br />

4.1.1.2. DSC<br />

The DSC used in this study was a power-compensated Perkin Elmer Pyris1 DSC with a<br />

water recirculating chiller at 12°C and an argon flow rate of 30 ml/min. The instrument<br />
