Discoverer: Smithin Tennant
Place: London, England
Year: 1804

Discovered in 1803 in London by S. Tennant. Iridium is a rare, precious metal which is hard, brittle and has a low ductility, which makes it a difficult material to work. In appearance, it is a lustrous, silvery metal. It has an abundance in the earth's crust of approximately 3x10-6 ppm. As might be expected from its position in the periodic table, iridium is stable to air and water and is not attacked by any acids, including "aqua regia" (this acid is used to separate iridium from the other platinum group metals). However, fused NaOH will attack iridium. It is extremely corrosion resistant and is used as an alloying agent with metals such as gold and osmium to produce alloys which are extremely hard and have good corrosion resistance. Iridium is also used in spark plugs, and its radioactive isotope, 192Ir is a medium energy gamma emitter used for industrial radiography.

Using finest materials, each density cube was lapped to 10x10x10mm by a famous company especialized in noble metals. Each one separately ground and polished it represents the theoretical density of the respective element by its weight. The weight is not affected by the laser inscription. Information such as element symbol, name and density is durable burned at the surface. Altogether 25 elements are planned in a complete set in a wooden case.

 Nice Iridium 4+ doped glass bead NEW!  Art. Nr. 004938  
Nice Iridium 4+ doped glass bead NEW!
magnify Click to zoom!

Glass bead doped with Iridium (Ir4+) Ions

Material: BaP:0.3Ir4+

Size about 13mm - Weight ~ 1.2g

Nice glass bead. Each one handmade of phosphate glass in our lab.

Doping glasses with Iridium is a very complicated task and several attempts failed due to the extremely low solublity of Ir in any glass matrix. Finally I was able to successful produce some Ir4+ containing glass samples. The max. concentration of Ir4+ is about 0.3 mol%. All attempts with higher amounts falied.
