使用X射线衍射仪对不同不同熔盐含量烧出的钛酸铁钠片晶进行XRD分析。当NaCl与原料的摩尔比为4，6时，XRD显示此时为纯的Na0.75Fe0.75Ti0.25O2相。而当NaCl与原料的摩尔比为2时，由于此时的熔盐含量不足以提供反应所需的反应环境，因此产物中除了Na0.75Fe0.75Ti0.25O2之外还存在着一些Fe2O3的峰。

The sodium ferric titanate flakes sintered with different molten salt contents were analyzed by XRD with X-ray diffractometer. When the molar ratio of NaCl to raw material is 4,6, XRD shows that the pure Na0.75Fe0.75Ti0.25O2 phase is present. However, when the molar ratio of NaCl to raw material is 2, the molten salt content at this time is not enough to provide the reaction environment required for reaction, so in addition to Na0.75Fe0.75Ti0.25O2, there are some Fe2O3 peaks in the product.
