| Abstract: | Order-disorder phase transformation has been observed in ZrS2 single crystals on annealing them at a temperature of 400 ± 10°C. Loss of sulphur, resulting in its deficiency, on annealing of crystals is thought to be the cause of the observed phase transformation. Evidence in its support, based on X-ray and electron diffraction results, is advanced. |
