Abstract

The thermistors are indispensable devices in experimental arrangements for electrical calibration of graphite calorimeters. The present experiments determine the two basic thermal constants in graphite – the thermal time constant, \( \tau_{g} \) and dissipation constant, \( \delta_{g} \) – of commercially-available VECO ultra-small bead thermistors; these constants are essential parameters in thermal modeling of graphite calorimeters. For the above-mentioned kind of thermistors, the dissipation constant in graphite is found to be approximately ten times larger than that in still air, whereas the thermal time constant in graphite is approximately one hundred times smaller than that corresponding to a thermistor placed in still air.
