Adhesion of colloidal hematite onto metallic surfaces I. Capacitive and counting measurements on silver and mercury
In this work the adherence of colloidal hematite to silver and mercury electrodes from 10-2 M NaClO4 solutions was studied by direct counting on SEM micrographs and admittance measurements. A linear relationship was found between the particle coverage on the electrode and the difference of the elect...
