 Differential Scanning Calorimetry (DSC) A
differential scanning calorimeter (DSC) measures energy flow into
(endothermic) or out of (exothermic) a specimen using a high
sensitivity measuring head. The technique measures between room
temperature and 1400o C under a flowing, inert gas the
following properties: specific heat, melting temperatures, transition
enthalpies, phase transformations, phase diagrams, crystallization
temperatures, degree of crystallinity, glass transition temperatures,
decomposition effects, reaction kinetics, and purity.
Samples can be powder, small pieces, or up to 5 mm diameter disks with
a thickness of 3 mm. Crucible materials are, graphite, platinum,
or alumina.
