一、引言从七十年代发展参比强度方法以来,X射线定量分析变得又简便又省时了,只要将被测物和标准物按重量1比1混合均匀制样,直接通过它们的最强衍射线的峰高比,即强度比,用简单的四则运算就能测到欲求的相含量。如果它们的最强衍射线有干扰,则可采用次强线或其它衍射线。国外报导用剐玉粉(α-Al_2O_3a Corudum)作为X射线强度标准,是因为它具有纯度高、化学性能稳定、原料丰富、容 I. INTRODUCTION Since the development of the reference intensity method in the seventies, X-ray quantitative analysis has become simple and time-saving, as long as the measured objects and standards by weight 1 to 1 mixed sample preparation, directly through their most The peak-to-height ratio of the strong diffraction line, ie, the intensity ratio, can be measured for the desired phase content using a simple four-run calculation. If their strongest diffraction lines interfere, then minor or other diffraction lines can be used. Foreign reports with jade powder (α-Al_2O_3a Corudum) as X-ray intensity standards, because it has high purity, chemical stability, rich raw materials,
