锐钛矿和金红石都是众所周知的 TiO2 稳定相。在现实样品中，TiO2 最有可能是这些相的混合物，而不是纯锐钛矿和金红石，因此定量分析极其重要。基本上可以利用晶体结构的差异通过X射线衍射（XRD）来确定平均比率，但是当尝试通过逐点扫描进行绘图时，这并不容易。本文介绍了新开发的投影式 XRD 成像的成功应用，这是一种极其快速且高效的方法。
Both anatase and rutile are well-known as stable phases of TiO2. In real-life samples, TiO2 is most likely to be a mixture of those phases rather than pure anatase and rutile, and therefore quantitative analysis is extremely important. It is basically possible to determine the average ratio by X-ray diffraction (XRD) using differences in the crystal structure, but it is not easy to do so when attempting mapping by point-by-point scanning. The present paper describes the successful application of newly developed projection-type XRD imaging, which is an extremely rapid and highly efficient method.
