For thermal conductivity measurements of ceramics like rutile, silica,alumina etc. What is the appropriate method at high temperature?
The hot-wire method is an absolute method for direct determination of the thermal conductivity, based on the measurement of the temperature increase of a linear heat source/hot wire (cross-wire technique, according to ISO 8894-1) or at a specific distance from a linear heat source (parallel-wire technique, according to ISO 8894-2).
Another variation, the so-called "Platinum Resistance Thermometer Technique" or "T® Technique", is described in ASTM-C 1113. Here an integral temperature measurement is carried out over the entire length of the hot wire; i.e. the hot wire is both heat source and temperature sensor at the same time.
I check your question, also I faced with such issue in my master thesis, however, there are some analysis like TGA and DSC but it has formula and some special protocol. please read the following paper.
If you can figure it out please let me know.
