To replace 00-004-0593.

Color: Light gray, yellowish brown.

Sample Preparation: This yttria stabilized phase was prepared at NBS, Gaithersburg, Maryland, USA, by Dragoo, Domingues (1982) from co-precipitation of the oxides.

 The powder was calcined at 620 C and then formed into a billet without binder, isostatically pressed, and then hot-pressed in an alumina die for 30 minutes at 1350 C with an applied stress of 28 MPa.

Structures: The structure of fluorite was determined by Bragg (1914).

Temperature of Data Collection: Pattern taken at 299(1) K.

Unit Cell Data Source: Powder Diffraction.
