Miassite is a mineral made of rhodium and sulfur, with the stoichometric formula . 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]
Its ability to be an unconventional superconductor was discovered at Ames National Laboratory in 2024.[3]
Miassite, covellite, parkerite, and palladseite, occur in nature, and are also made in labs as superconductors. Miassite is the only one found to also have unconventional superconductivity. [4]
