Abstract A simple and rapid quantitative method for determining RE2O3 in rare earth oxide by X-ray fluorescence spectrometry was developed. A new method for manufacturing sample was brought up. The sample pedestal plate was lathed with polytetrafluoroethylene. A filter paper located in the sample pedestal plate was used to absorb 1 mL analytical solution, dried under infrared lamp or in stove and measured by X-ray fluorescence spectrometry with a 6μm covering film. No remainder was detected in the sample pedestal plate. Vanadium was confirmed as the internal standard to compensate the influence of the location of absorbing filter paper within the sample pedestal plate, the analytical range was large, the accuracy and precision were satisfactory, the results agreed with other methods, and the method has been used in routine analyses for ten years. Also the method for manufacturing sample has been applied to a variety of materials.
