SrxBa1-xNb2O6(x=0.5) ceramic powders were synthesized by the aqueous organic gel routes. The desired metal cations were chelated in a solution by using citric acid and ethylenedi-aminetertraacetic acid (EDTA) as the chelating agents.

• 以柠檬酸和乙二胺四乙酸为配位剂与金属离子配位；以水作为溶剂；采用有机凝胶法合成了纳米SrxBa1-xNb2O6(x=0.；5)陶瓷粉体
