New LFA 467 HT HyperFlash Sample Holder – Dedicated to Liquid Metals
For LFA measurements, a defined sample thickness is required because the thermal diffusivity (a) is proportional to the Square of the sample thickness (d):a ~d2. This demands high precision to obtain the exact thickness value. In addition, the heat flow through the outer container walls in the axial direction can be critical for sample holders for liquids. Furthermore, it should be considered that measurements on metals into the melt could easily destroy the sample holder.
