I am looking for advice on how to prepar a HTXRD sample (mounting techniques, stage preparation, etc...). The ribbon heater is tantalum (brand new). The sample contained ammonium di-hydrogen phosphate. The atmosphere is air.
I hope to reach at least 1100C, but have had the ribbon break before 750C. Corrosion? or can the sample lower electrical resistance? Please, any advice. All the best, Blaise
