Chemistry:Lead apatite

From HandWiki

Lead apatite is a generic name for apatite-structure materials that contain lead as the divalent cation. A Copper-doped lead-apatite has been proposed as a room-temperature superconductor. A number of minerals are known. All have a hexagonal crystal structure.
