钠钨青铜的低温水热合成的研究

Research on hydrothermal synthesis of Sodium Tungsten Oxide Bronzes

该文采用低温水热合成法制备出x约为 0 .4的导电材料钠钨青铜晶体。通过条件实验确定了水热法制备钠钨青铜的较佳工艺条件 ,提出了目标产物提纯方法。用便宜、易得的KBH4 代替NaBH4 作了探索实验 ,得到了与目标产物接近的产品。红外光谱表明产物具有良好的红外光吸收性能。

A method of hydrothermal synthesis of sodium tungsten brozes has been discussed.The purity and characterization of the products have proved to be influenced by the reaction pH as well as the concentration of the reagents.In addition, sodium borohydrides has been replaced by potassium borohydrides to reduce the sodium tungstate and similar products have been obtained. At last, IR spectrum and conductivity of products have been determined.
