钠钨青铜（Na_xWO_3）晶体的制备及其成分、结构测试

Preparation of Sodium Tungsten Bronze Crystal and Measurment of the Content and Structure

文中采用熔盐电解法，电解钨酸钠与三氧化钨熔盐制备出系列钠钨青铜晶体，选用离子选择电极分析法快速、简便、可靠地测定了晶体中的钠含量，并通过Ｘ－射线粉末衍射确定了晶体的晶型结构及晶格常数ａ．

In this paper,that a series of sodium tungsten bronze crystals were prepared by electrolysis of molten salts containing sodium tungstic and tungstic oxide was reported.The contents of sodium in the brones were determined by ion selective electrode analysis.The crystal structure and the lattice parameter were deduced by X-ray powder diffraction.
