Thermal Diffusivity Thermophysical Properties Research Laboratory, Inc. Phone : 765-463-1581 Thermal Diffusivity Thermal diffusivity measures the change of temperature which would... of temperature between it's faces. TPRL provides three methods to measure diffusivity. The most common is the laser flash, which can be run over a temperature range of liquid nitrogen... the thermal diffusivity of good conductors over a temperature range of room temperature to 800C. However, the laser flash is generally the preferred method for these materials. Still...

diffusivities range from 0.001 to 10 (a range of 10 ^ 4) over a temperature range from 80 to 2500K (-315 to 4050 F). The method uses small easy to fabricate samples and results can... be obtained within seconds. The thermal diffusivity () is not only important in its own right, but it also offers a convenient, economical and accurate method of determining... insensitive, obey well-known physical laws and can be measured readily on small samples. It is possible to either measure these properties on the same sample used for diffusivity...
