Электрофизические и электрохимические свойства поликристаллов, спеченных из субмикронных диэлектрических алмазных порошков

Abstract

The results of research of electrophysical properties and electrochemical behavior of electrodes based on the sintered polycrystals of synthetic diamond dielectric powders of submicron dispersity in the background electrolytes 1 М KCl and 0,5 M H2SO4 and electrolytes, containing the oxidizing-reduction system K3[Fe(CN)6]/K4[Fe(CN)6] have been presented. The electrochemical activity of partly graphitized composites in the studied electrolytes and its dependence on the volume resistance of samples are determined. The influence of electrochemical modification of electrode surfaces on the electro-catalytic properties of studied materials is shown.
