Abstract
The temperature-composition phase diagram of the HgTe-HgI2 system was determined from 0 to 45 Mol-% HgI2 between 25 and 670 degrees C using Debye-Scherrer powder X-ray diffraction techniques and differential th ermal analysis. Solid solutions of HgTe and HgI2 with the cubic, zinc blende-type structure exist above 300 degrees C, having a maximum solu bility of 11.7 +/- 0.8 Mol-% HgI2 in HgTe at 501 +/- 5 degrees C. The known monoclinic compound Hg3Te2I2 is formed by a peritectic reaction upon cooling at 501 +/- 5 degrees C, with the peritectic point at appr oximately 37 +/- 4 Mol-% HgI2.
