Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. [25] Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. [26] Rhodium has both a higher melting point and lower density than platinum.

Rhodium is a chemical element that is a rare, silvery-white, hard, and chemically inert transition metal and a member of the platinum group. It has the chemical symbol Rh and atomic number 45. It is composed of only one isotope, 103 Rh. Naturally occurring rhodium is found as the free metal, alloyed with similar metals, and never as a chemical ...
Rhodite or rhodian gold is a naturally occurring alloy of gold and rhodium found in gold ore. Gold ore containing 34 to 43% rhodium was reported from Mexico and Colombia in 1825. [1] The alloy displays brittle tendencies and has a density of 15.5 - 16.8 g/cm 3. [2]
Miassite is a mineral made of rhodium and sulfur, with the stoichometric formula Rh 17 S 15. It was named after the Miass River in the Urals. [1] It is a superconductor and an unconventional superconductor. Naturally occurring miassite is too brittle, so it is made in a lab for superconductor research. [2]
