Platinum group metals are used as alloying additives. PGMs may be used to make crucibles used to grow single crystals, particularly of oxides. Platinum group metal alloys are used to make electrical contacts, electrodes, thermocouples, and circuits. Iridium and platinum are used in medical implants and pacemakers.
The platinum-group metals (PGMs) are iridium, osmium, palladium, platinum, rhodium, and ruthenium. In general, PGMs exhibit high density, high electrical conductivity, high melting points, and low reactivity. …
Separation of Platinum Group Metals (PGM) from Liquid Media. Technetium (particularly Tc7+), ruthenium (particularly Ru4+), rhodium (particularly Rh4+ and Rh3+), rhenium (particularly Re7+), and iridium (particularly Ir4+ and Ir3+) can be ionically grouped with the Platinum Group Metals (PGM) because they form stable oxyanion complexes. 43.
The six elements of the platinum group – ruthenium, rhodium, palladium, osmium, iridium and platinum – are referred as platinum-group metals (PGM).
