Process for the production of refractory metal plates and expanded metal grids platinized on one side

摘要

A process for the production of refractory metal plates platinized on one side, in which refractory metal plates of predetermined dimensions are tightly, form-fittingly joined together back to back, are coated with platinum on their exposed surfaces by melt electrolysis and the plates are then separated one from the other. These plates may be processed into expanded metal grids platinized on one side. These refractory metal plates platinized on one side and the expanded metal grids platinized on one side produced therefrom may be used highly advantageously as anodes in electrolytic and electroplating processes.
