Abstract
Frequency dependent photoacoustics have been used to measure the thermophysical properties of technical graphites between room temperature and 1000 K. A photoacoustic cell has been built which allows one to detect thermal waves in both thermal transmission and reflection. Various measurement procedures have been developed based on frequency scans at different temperatures and temperature scans at a constant frequency of the thermal wave.KeywordsThermal WaveGraphite SamplePhotoacoustic CellThermal TransmissionPhotoacoustic MeasurementThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
