Nano-sized NaNbO 3 powder has been successfully prepared by aqueous solution-gel method. The phase evolution of NaNbO 3 powder is investigated by TG/DSC, X-rays spectra, FT-IR, and Raman spectra. The results show that the pure NaNbO 3 phase has been obtained at about 375°C, which is ...
1. Strontium titanate nanometer powder used for multi layer ceramic capacitors was prepared from Sr(NO3)2–Ti(OC4H9)4– H2O–C2H5OH systems by the solution–sol–gel method. 采用溶液–溶胶–凝胶法,从Sr(NO3)2–Ti(OC4H9)4–H2O–C2H5OH体系制备多层陶瓷电容器用的纳米SrTiO3粉体。
BaBi2Nb2O9 powders and their ceramics were prepared by aqueous solution–gel method. The phase evolution and microstructure of samples including powders and ceramics were determined by X-rays, SEM. An homogenous BaBi2Nb2O9 powder was observed after thermal treatment at the temperature as low as...

The sol–gel method can provide glasses and ceramics via the transition states of viscous gels produced by polymerization of raw materials such as metal alkoxides under more gentle conditions (room temperature) than those of the conventional melting techniques (traditional glass). Therefore, the sol...
