Specific Heat Capacity
Specific heat capacity is expressed as a quantity of heat necessary to rise the temperature
of unit mass of the substance by one unit.
TPRL has four different pieces of equipment available for the direct measurement of the specific
heats of materials. Depending on the temperature range needed and the atmosphere conditions
required, either one or the other or sometime both pieces of equipment will be used.
A Perkin-Elmer Differential Scanning Calorimeter (DSC) is used to measure
the specific heats of a material from liquid nitrogen to 600°C.
A Netzsch differential scanning calorimeter is used to measure
specific heats from room temperature to 1400°C.
The Netzsch STA is used to measure
specific heats from liquid nitrogen to room temperature. This is typically only used when a gravimetric analysis is also run.
For conducting solids, the multi-property apparatus can measure the
specific heat. However, since the DSC's are equally accurate but more economic, they are typically used.
Still not sure what is the best testing method for your material? Use our
Testing Method Selector Tool to help you decide.
