1. The majority of rhodium is used as a catalyst in catalytic converters. It is also used to catalyze industrial processes.
2. It is a hard silvery-white metal,also used in the jewelry industry, used as a hardening agent in alloys with Platinum,classified as a transition metal from the platinum group, to produce a reflective white surface in a process called rhodium flashing. It is also used as a coating for sterling silver to reduce the chance of tarnishing. Plated rhodium is sometimes used for optical instruments.
3.It is also used in some alloys containing platinum and palladium for hardening and to provide increased corrosion resistance.
4.Alloyed with Platinum to make heavy duty electrical contacts such as high performance
5.It can also be used as an electrical contact material.
