Rhodium Bath Rhoduna Diamond Bright

The rhodium concentrate is used for the decorative surface coating of e.g. jewellery, watches and spectacle frames. It produces a hitherto unattained brightness and brilliance, extremely abrasion-resistant deposit. Layer thicknesses of up to 5 µm can be deposited.

The rhodium bath is used in a conventional electroplating unit. The free acid content is 22 g/l for a new bath. It increases during the service life and with repeated regeneration. This reduces the deposition rate, but this can be compensated by extending the exposure time.
