Al sub(2)O sub(3)-HfO sub(2)-Y sub(2)O sub(3) phase diagram. I. Isothermal sections at 1250 and 1650 degree C

Al sub(2)O sub(3)-HfO sub(2)-Y sub(2)O sub(3) phase diagram. I. Isothermal sections at 1250 and 1650 degree C

Isothermal sections at 1250 and 1650 degree C in the Al sub(2)O sub(3)-HfO sub(2)-Y sub(2)O sub(3) phase diagram are plotted for the first time. Phase equilibria are established at these temperatures. No ternary compounds and appreciable solid solution regions based on binary compounds are found in...

Zusammenfassung:Isothermal sections at 1250 and 1650 degree C in the Al sub(2)O sub(3)-HfO sub(2)-Y sub(2)O sub(3) phase diagram are plotted for the first time. Phase equilibria are established at these temperatures. No ternary compounds and appreciable solid solution regions based on binary compounds are found in the ternary system.
