摘要：

A Bi2O3 compound which is unknown to date has been synthesized at 800 degrees C on a BeO substrate. alpha-Bi2O3 at 800 degrees C undergoes a phase transition to a metastable new compound named omega-Bi2O3 which in turn transforms to stable delta-Bi2O3 at 900 degrees C. X-ray powder diffraction data were collected, indexed, and refined in order to obtain a unit cell (probable space group P (1) over bar: a = 7.2688(4), b = 8.6390(6), c = 11.9698(8) Angstrom, alpha = 87.713(6), beta = 93.227(6), gamma = 86.653(4)degrees. This compound is of interest for the thick films circuits and sensors technology. (C) 1997 International Centre for Diffraction Data.
