Testing Thermal Conductivity of Powders

The testing of powders is a difficult measurement, due to the contact resistance created by loose solids.

Hot Disk Transient Plane Source

The Hot Disk has the unique ability to be able to test thermal conductivity on powders of small and large particles. This is due to the method having a variety of sensor diameters and variable test times. The sensor sizes and test times may be increased as the particle size increases to create better contact between the sensor and sample.
