| 摘 要： | 本文采用 1:2HCl将氮化钛与其它氮化物分离,将分离出的TiN残渣加浓H_2SO_4-K_2SO_4加热冒烟使其分解,加入过量的NaOH,加热蒸馏,以溴化钠作电解液,用双铂电极在30mA恒电流下进行电解,终点以死停终点法指示。终点到达时停止电解,记录电解时间,以此计算TiN的含量。

| Abstract: | TiN is separated from orther Nitride by 1:2 Hcl, and the residue of TiN is heated with concentrated H2SO4-K2SO4 until the smoke rises from it followed by adding exceeded NaoH and by heating distillation. Using NaBr as electrolysis solution, the double platinum electrode is used to conduct the electrolysis. At the constent current of 30 mA. When it reaches the end point indicated by the dead stop method, record the time so as to calculrte the conten of TiN. |
