I am looking for simple way to calculate the thermal conductivity K of my samples (ceramic), in my uni using old equipment "Cusson" but with unacceptable results, so I need other way/ modern device name to do that, with thank you in advance to all..
Hi Ahmed, I would recommend TA Instrument's FOX50 Heat Flow Meter instrument tests using two thin round silicon rubber pads. First you measure total thermal resistance of the two rubber pads only, and then you measure total thermal resistance of your 50-51 mm diameter 10-13 mm thick ceramic sample sandwiched between the two rubber pads. Make sure that the full thermal equilibrium has been reached. Then thermal conductivity will be calculated as thickness of your sample (in meters) divided by the difference between the two measured total thermal resistances. Total thermal resistance equals temperature (degrees C) difference divided by the measured heat flux (Watts per square meter).
