Rhodium (Rh) Metal

Rhodium (Rh) is a silvery-white metal in the platinum group. It has a very reflective surface. It is very hard, durable, and highly resistant to corrosion. It is harder and has a higher melting point than platinum and palladium, making it a useful hardening element in alloying. Rhodium has the highest electrical and thermal conductivity of the group.

Purities Available: 99.8% to 99.95%
Typical Applications

Rhodium is a highly useful catalyst in several industrial processes, with its major use in catalytic converters for cars where it reduces nitrogen oxides in exhaust gases. Its reflective nature finds it useful in the jewelry industry, and it is used to coat optic fibers and optical mirrors and for crucibles, thermocouple elements, and headlight reflectors.
Its low electrical resistance and corrosion resistance make it useful as an electrical contact material.
