Abstract

In an improvement of the method disclosed in the parent Specification for preparing platinum carbon rods as electrodes in a vacuum deposition process, the composition of the mixture ranges from above 83,33% up to 90% platinum or below 75% to 10% platinum with the remainder carbon. In a further modification the platinum is replaced by iridium up to a maximum of 50% by weight of the platinum so that the total metal content ranges from 10% to 90% by weight of the mixture with the remainder carbon.
