WebMelting of substances is a commonly observed phase change from a crystalline solid to an amorphous liquid. There is a typical assumption that loss of crystalline structure while heating in a DSC at typical rates of 1 to 25 °C/min is True (thermodynamic) Melting. WebThe DSC conditions to identify the phase transition points are given as follows: Thawing cycle: -15 C to 40 C at a heating rate of 2 C/min in nitrogen atmosphere (25ml/min). Freezing cycle: 40 C to -5 C at a cooling rate of 2 C /min. Liquid nitrogen was used …
