What is Rhodium? December 13, 2018 10:56

Rhodium is a silver-white hard metal often found in platinum ores. It is the most expensive precious metal. In its natural solid state Rhodium is far too hard to work, but it is used as an alloy in the smelting of platinum and palladium. 

Rhodium plating is a metal deposition process used to coat materials with a decorative and protective layer of rhodium. It is one of the rarest and most valuable precious metals. Both platinum and rhodium are noble metals that resist corrosion. In fact, rhodium is even more expensive than platinum.
