Dear all :
May anyone share with me a Graph showing the curves for Temperature vs Thermal Conductivity, and Temperature vs. Electrical Conductivity/Seebeck Coefficient (in the same Graph) for distinct type of materials: (semiconductors, semiconductor alloys, metals, semimetals, etc.) showing the points in the range up to 1000°C ?
This is for use in Thermoelectric materials.
If someone can send it to me I'll appreciate it a lot
Thanks !
Dear Franklin,
You will get these graphs in many literature. But it is not possible to get these graphs upto 1000 degree celsius for all materials.
Anyway, I think it is better to get these results by your own Experiments because standard data always doesn't match with your working material due to impurities and difference in microstructures.
If anything you want regaring the Experimental details for these I can tell you ( but upto 600 degree Celsius)
Love and Regards

Figure 8 in the linked PDF is close to what you are looking for. Remember, electrical conductivity and resistivity are inversely related.
Dear all, the question was already discussed within RG.

The three parameters are interrelated by the Wiedemann–Franz law. The links below gives additional information. My Regards

Dear Franklin,
Thanks.
If you want any input from me, I will as I can. I like this type of work.

Dear Franklin,
I have studied the neutral temperature and inversion temperature of iron - copper thermocouple by simple, low cost set up designed by my self.
Right now, for better accuracy , I am using PID controlled 600 degree oven and more accurate nano voltmeter ( manufactured by Agilent Technologies, now Keysight ) for voltage measurement.
Love and Regards
