摘要
确定了信噪比的数值,在此数值下,处理 X 射线衍射数据的方法可显示强度小于背景噪声分量的反射。在 α-石英的微弱反射上演示了该方法的可能性。这种处理 X 射线衍射数据的方法提高了 X 射线相分析在确定多相材料的定性相组成方面的可能性,这些多相材料含有少量(低至 0.1 wt.%)几种(最多八种)相。
Possibilities of the X-ray diffraction data processing method for detecting reflections with intensity below the background noise component
The values of the signal-to-noise ratio are determined, at which the method of processing X-ray diffraction data reveals reflections with intensity less than the noise component of the background. The possibilities of the method are demonstrated on weak reflections of α-quartz. The method of processing X-ray diffraction data makes it possible to increase the possibilities of X-ray phase analysis in determining the qualitative phase composition of multiphase materials with a small (down to 0.1 wt.%) content of several (up to eight) phases.
期刊介绍:
Powder Diffraction is a quarterly journal publishing articles, both experimental and theoretical, on the use of powder diffraction and related techniques for the characterization of crystalline materials. It is published by Cambridge University Press (CUP) for the International Centre for Diffraction Data (ICDD).
