High-temperature study of CaZrTi2O7

Abstract

Previously reported anomalous thermal expansion effects in the 1200–1500°C range for hot-pressed CaZrTi2O7 were shown to be due to irreversible bloating effects, from occluded gases. X-ray diffraction and differential thermal analysis of ordered CaZrTi2O7 did not reveal evidence of a solid-state transformation at temperatures up to 1450°C. © 1992 Elsevier
