Effects of Sintering Temperature on the Structure and Conductivity of LiSn2P3O12 Prepared by Mechanical Milling Method

摘要：

LiSn2P3O12 has been prepared using mechanochemical milling method and sintered at 700 ℃, 800℃, 900℃ and 1000 ℃ for 8 hours. All samples sintered up to 900℃ show a rhombohedral structure. However, the sample sintered at 1000 ℃ possessed a monoclinic structure. This is attributed to the rotation of skeleton LiSn2PsO12 as indicated by the change in the a and c parameters of the sample. The sample sintered at 700 ℃ shows the highest bulk conductivity of 1.65×10-6 S cm-1 and the lowest bulk activation energy of 0.09 eV. The grain boundary activation energy of the samples decreases with increase in sintering temperature due to enhancement in grain contacts.
