Rhodium was discovered in by English chemist William Hyde Wollaston shortly after he had discovered the element palladium.

Wollaston extracted rhodium from a piece of platinum ore that he had obtained from South America. Rhodium often occurs with deposits of platinum and is commonly obtained from the mining and refining of platinum.

Wollaston was first alerted to the possibility of a new element existing in platinum ore by the French chemist Hippolyte-Victor Collet-Descotils, who believed that the red color of some platinum salts was due to the presence of an unidentified metal. After a series of chemical reactions, Wollaston was able to remove the platinum and palladium from the sample of platinum ore.

He was left with a dark red powder — which turned out to be sodium rhodium chloride, according to Jefferson Lab. The main use for rhodium is in catalytic converters designed to clean vehicle emissions. Without rhodium catalysts, the air in our cities would be much worse due to vehicle exhausts. Since rhodium is quite brilliant and resistant to tarnishing, it is used as a finish for jewelry, searchlights and mirrors.

It is also alloyed with platinum for aircraft turbine engines. In the chemical industry, rhodium is used as a catalyst in the making of nitric acid, acetic acid and hydrogenation reactions, according to the Royal Society of Chemistry RSC.

Other uses for rhodium are coating optic fibers, crucibles, thermocouple elements and headlight reflectors. Since it has a low electrical resistance and is highly resistant to corrosion, it is used as an electrical contact material as well, according to RSC.
