A new technique is presented for the prepn. of DSA type electrodes. In this technique, the precursor is rapidly decompd. on the substrate by treatment in an induction electromagnetic field. The effects of the rapid heating of H2IrCl6.6H2O precursor on Ti substrate on the morphol. and the compn. of the coating are presented. Formation of metallic Ir is obsd. using this technique.
