ABSTRACT
The yttrium environment in liquid Y[sub 2]O[sub 3] at 2770 K has been measured with anomalous x-ray scattering, aerodynamic levitation, and laser heating. The Y–O coordination of 6–7 and the Y–Y coordination of around 12 imply that the close packing of the high-temperature (H-type) solid phase is preserved on melting, in contrast to the large structural changes exhibited by Al[sub 2]O[sub 3]. The unusually sharp main diffraction peak implies a high degree of chemical order and mirrors the diffraction pattern of the H-type phase. © 2003 American Institute of Physics.
