Rhodium plated by both electroplating or evaporation is extremely tricky and valuable for optical devices.[fifty two]
Within the Asia Pacific region, rhodium pricing dynamics are drastically influenced by sturdy industrial expansion and increasing manufacturing sectors, particularly in China and India. The location's significant demand for metals is driven by its Energetic design market and raising investments in infrastructure initiatives.
There are many means to inform if jewelry is rhodium plated, but generally, just a jeweler can confirm this. Nevertheless, you'll be able to test both of these tests techniques:
Other than catalytic converters, some programs utilizing rhodium are as being a catalyst for nitric acid, in themocouples, and also to coat optic fibers and optic mirrors.
