Low-Temperature Synthesis Of Bi_(3.15)Nd_(0.85)Ti_30_(12) Nanoplates By A Sol-Gel-Hydrothermal Method

摘要

Well-crystallized pure Bi_(3.15)5Nd_(0.85)Ti_3O_(12) (Bndt) nanoplates with rim sizes of 150-200 nm and thickness of 20-30 nm have been successfully synthesized at a temperature as low as 160℃ by a novel sol-gel-hydrothermal route, which combined the conventional sol-gel process and the hydrothermal method. It is believed that the gel precursor and hydrothermal environment play an important role in the formation of Bndt nanoplates at a low temperature. The density of sol-gel-hydro-thermal-derived Bndt ceramics was higher than that of sol-gel-derived ceramics.
