    OverviewCharacteristicsHistoryProductionApplicationsPrecautionsExternal links

    Rhenium is a silvery-white metal with one of the highest melting points of all elements, exceeded by only tungsten and carbon. It also has one of the highest boiling points of all elements, and the highest among stable elements. It is also one of the densest, exceeded only by platinum, iridium and osmium. Rhenium has a hexagonal close-packed crystal structure, with lattice parameters a = 276.1 pm and c = 445.6 pm. Its usual commercial form is a powder, but this element can be consolidated by pressing and sinteringi
