TPRL, Inc. uses a Netzsch Differential Scanning Calorimeter for measuring
specific heat at high temperatures (500°C to 1400°C.
The Netzsch DSC operates according to the heat flux principle. Using this method, a sample and a
reference are subjected to a controlled temperature program (heating, cooling or isothermal). The actual measured
properties are the temperature of the sample and the temperature difference between sample and reference. From the raw
data signals, the heat flow difference between sample and reference can be determined.
By comparing this heat flow rate with the rate measured during the heating of a known mass of sapphire, the
specific heat is calculated. The experiments are performed under computer control and specific heat is calculated
in Joules/(gm K) and BTU/(lb F) (which equals Cal/(gm C) ) at the related temperature intervals. The DSC's are
periodically checked by running either NIST sapphire or alumium as a sample and the results are compared to the
