Phasenänderungen im System Er2O3—TiO2

摘要

The system Er2O3−TiO2has been investigated by microscopic and X-ray procedures. A phase diagram for the solidus range has been proposed. The pyrochlore phase is homogeneous from 33.3 to 50 mole Er2O3at 1550°C. Beyond 50 and up to 57 mole Er2O3, the fluorite phase is homogeneo
