This week’s topic: Measuring Thermal Diffusivity using Laser Flash Analysis (LFA)

In the LFA, a light pulse heats the front surface of a plane-parallel sample and the resulting temperature rise at the sample´s rear face is recorded as a function of time. The higher the Thermal DiffusivityThermal diffusivity (a with the unit mm2/s) is a material-specific property for characterizing unsteady heat conduction. This value describes how quickly a material reacts to a change in temperature.thermal diffusivity, the faster the temperature rise reaches the rear face.
