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.
