    摘要: On the other hand, the possibility of estimating the dopant ratio of a metal element to each ceria crystalline particle using integral-width or half-width obtained by XRD was considered as follows: an XRD peak is shifted depending on the dopant ratio of La to ceria; when La increases, an XRD peak is shifted to a lower angle; in XRD performed on a raw material obtained by mixing ceria crystalline particles having different dopant ratio, peaks corresponding to the respective dopant ratio exist close to each other; as a result, a peak width is widened; accordingly, the dopant ratio of a metal element to each ceria crystalline particles are supposed to vary when integral-width and half-width obtained by XRD are large. Thus, it was revealed for the first time that integral-width and half-width obtained by XRD indicate variations in dopant ratio. It should be noted that from the direct proportional relationship between the dopant ratio x and the integral-width for dopant ratio ranging from 0.35 to 0.45, integral-widths obtained by XRD are derived to be 0.10 to 0.30 for dopant ratio ranging from 0.35 to 0.45, and half-widths are derived to be 0.10 to 0.30 similarly.

    摘要翻译: 另一方面,使用通过XRD得到的整体宽度或半宽度来估计金属元素与每个二氧化铈晶粒的掺杂比率的可能性被认为如下:XRD峰值根据La的掺杂剂比率而偏移 二氧化铈 当La增加时,XRD峰移动到较低的角度; 在通过混合具有不同掺杂剂比率的二氧化铈晶粒获得的原料进行的XRD中,与各自的掺杂剂比例相对应的峰彼此接近; 结果,峰宽变宽; 因此,当通过XRD获得的整体宽度和半值宽度时,假定金属元素与每种二氧化铈晶体颗粒的掺杂比变化。 因此,首次揭示了通过XRD获得的积分宽度和半值宽度表示掺杂剂比例的变化。 应当注意,从0.35至0.45的掺杂剂比率的掺杂剂比x和积分宽度之间的直接比例关系,通过XRD获得的积分宽度导出为0.35至0.45的掺杂剂比为0.10至0.30 ,并且半宽度类似地导出为0.10至0.30。
