Thermal Diffusivity and Thermal Conductivity (LFA)

With all Netzsch Laser Flash Analysis (LFA), the thermal diffusivity and specific heat capacity can be determined. This data is then used for the calculation of thermal conductivity.

The characterization of highly conductive materials at cryogenic and moderate temperatures or ceramics and refractories at elevated temperatures is of high interest. Many challenges can only be met with precise knowledge of thermal diffusivity and conductivity. One accurate and robust solution for the direct determination of thermal diffusivity is offered by the Laser/Light Flash Methods (LFA). The thermal conductivity is then calculated by using the LFA results. The software already includes various corrections, calculation models, and mathematical operations for improved evaluation of the LFA data.

NETZSCH instruments are based on the respective instrument and application standards for LFA (e.g., ASTM E1461, DIN EN 821, BS EN 1159-2, ASTM C714, etc.).
