摘要: 对LiNd(PO3)4晶体分别在N2气和空气下进行了TG和DTA热分析研究,给出TG和DTA曲线,讨论了LNP晶体在N2气和空气下不同的热分解机理.得到分解产物分别为Nd4(P2O7)3和NdP2O7.

关键词: LiNd(PO3)4晶体, 热重分析, 差热分析

Abstract: The study of LiNd(PO3)4 crystals was carried out by TGand DTAin different atmosphere (nitrogen and air). The TGand DTAcurves were presented. The thermal decomposition mechanisms in nitrogen and air were discussed. The results indicate that the major products of thermal decomposition are Nd4(P2O7)3 and NdP2O7 in N2 and air, respectively.

Key words: LiNd(PO3)4 crystal, Thermogravimetry(TG), Differential thermal analysis(DTA)
