Fig.1 showed the XRD patterns of the Li4Ti5O12/A composites with different B added from 1to 2wt% together with the pristine Li4Ti5O12 sample for comparison. It was found that the diffraction patterns of all the samples synthesized are similar, with all the peaks indexed in a cubic spinel structure with a Fd3m space group . No impurity pexed with the standard peak such as Ti oxides (TiO2) could be detected in the samples. The strongest peak is corresponding to the (111) plane. No obvious shift of the diffraction lines were found, each peak was well indexed in the JPCDS card No.49-0207, which indicates the phase of the samples were not changed afterA modified. The lattice parameter “a” for Li4Ti5O12 calculated using a powder cell program is 8.361A, which agrees well with the literature. 图一是纯样 Li4Ti5O12以及添加质量比为1%-2%的B物质所合成的 Li4Ti5O12/A复合物质的XRD图谱，从图上可以看出：所有合成物质的衍射峰是一致的，所有的峰都符合Fd3m点群的立方尖晶石结购，没有杂质峰（TiO2）存在，最强的峰值对应的(111)面，没有明显的转移的衍射线,每个峰被发现与在JPCDS No.49-索引卡片中的峰一致，证明B物质的修饰没有改变Li4Ti5O12的结构, 帮忙整理一下，感觉自己写的啰哩啰唆，又不想删掉句子，最后一句是因为老师让把晶包参数计算出来加进去，因为是几个不同的样品，不知道应该写一个的，还是写多个的，他们的晶包参数都差不多，帮忙想想怎么写，应该加在什么位置,谢谢 [ Last edited by 爱与雨下 on 2011-9-19 at 15:02 ] |

Figure 1 shows the XRD patterns of the pure Li4Ti5O12 sample together with the Li4Ti5O12/A composites of different content of B ranging from 1 wt%to 2wt%. The diffraction patterns of all the synthesized compounds are well in agreement with each other, with all the peaks indexed in a cubic spinel structure with a Fd3m space group. No impurity peaks such as Ti oxides were detected. The strongest peak corresponds to the (111) plane and no obvious shift of the diffraction was observed. Each peak was found to be well indexed in the JPCDS card No.49-0207, which indicates that the structure of Li4Ti5O12 doesn’t change with the modification of B. The lattice parameter “a” for Li4Ti5O12 calculated by a powder cell program is 8.361A, which is corresponding to the value of literature. 能力所限，希望对你有帮助。  |
