Compare of liquid-state methods synthesizing Nano-BaTiO3Author(s): Wang Jing, Ding Shi-Wen, Lv Shu-Fang
Nano-BaTiO3 powder is synthesized with TiCl4 and Ba(OH)2 by different liquid-state methods, such as atmospheric method, high-pressure thermal method and microwave method. Its phase, shape and capacity is investigated byXRD, TEM, SEM, SAXS, LCR.XRD of the series of the nanometer powder demonstrates that BaTiO3 of cubic system has been prepared. Through TEM we found the products have a shape of uniform, substantially spherical particles. Powder synthesized by microwave method has the least grain-size, the lowest sintering temperature, and the best dielectric capacity.
