Electrochemical synthesis of ceramic materials. 5. an electrochemical method suitable for the preparation of nine metal nitrides

摘要

We discuss an electrochemical approach suitable for preparing nine metal nitride precursors and the corresponding metal nitrides. The method involves anodic dissolution of a metal electrode in a single-compartment electrochemical cell containing an electrolyte solution consisting of liquid NH_3 and NH_4X(X=Br or Cl). Following evaporation of the solvent and calcinations of the resulting powder at temperatures between 375 and 1100 deg C, we obtain the metal nitride corresponding to the anode material.
