Verification of Existence of Cubic Zirconia at High Temperature

Verification of Existence of Cubic Zirconia at High Temperature

The existence of the high-temperature cubic form of ZrO/sub 2/ was verified with an x-ray diffractometer. The 200 and 002 doublet was taken as the best indicator of the phase change, and the tnansformation was found to occur at 2285 plus or minus 15 deg C with first order kinetics. The structure was...

Zusammenfassung:The existence of the high-temperature cubic form of ZrO/sub 2/ was verified with an x-ray diffractometer. The 200 and 002 doublet was taken as the best indicator of the phase change, and the tnansformation was found to occur at 2285 plus or minus 15 deg C with first order kinetics. The structure was found to be face-centered cubic of the CaF/sub 2/ type, and the cell constant was measured as 5.272 A. (D.J.C.)
