Rhodium is mainly used in the production of alloys with the platinum, with resulting high hardness and resistance materials. These alloys are used in electric ovens in glass industry, in turbine reactors, in the production of thermocouples and in catalytic nets for different chemical reactions, in particular the oxidation of ammonia into nitric oxide. The metal also finds some application in jewelry for the coating of silver objects, in the production of projectors, in the production of emitting and receiving circuit components, etc.
In jewelry, rhodium is used as a fine film coating of white gold jewels, by electrolytic deposit. This process improves the aspect of the jewel, turning it very white and more resistant.
