Currently using medium density PTFE seal tape to secure samples to the quartz sample holder. This is only able to with stand temperatures up to about 300C.
For these higher temperatures, I often see ceramic adhesives being suggested. However in my experience with an Al2O3 ceramic paste adhesive, the magnetic properties are greatly affected when used to mount the sample.
Hence in order to measure magnetic properties such as coercivity, remanance, saturation moment etc I need a suitable adhesive which is able to with stand temperature up to 350C while not interfering with the results.
Thanks in advance
Some polyimides (such as Kapton:

have temperature resistances akin to PTFE which is generally regarded as one of the best - also combining chemical inertness. However, I suspect you will have to look for inorganic materials (as you have done) for sustained performance at these temperatures. Glass frit compounds are available which may work. I think you'll have to look around and see if anyone else has direct experience of similar measurements and issues.
