That was Brian Clegg brightening up the Periodic Table with the iridescent tale of Iridium. It has the greatest density of any element in the group. The black residue left behind was commonly thought to be graphite before Tennant investigated further. Iridium has the 10thhighest melting point among all chemical elements. Copyright of and ownership in the Images reside with Murray Robertson. It wasn't until 1842 that a scientist, Robert Hare, was able to obtain a sample of pure iridium. Iridium has a melting point of 2410C, a boiling point of 4130C, a specific gravity of 22.42 (17C), and valence of 3 or 4. A member of the platinum family, iridium is white like platinum, but with a slight yellowish cast. The metal is very hard and brittle and is the most corrosion-resistant metal known. Iridium is not attacked by acids or This was explained in a manner similar to that for electron beam welding, a highly concentrated heat source and a relatively fine fusion zone microstructure.

Melting of Ir is performed by induction melting, electron beam melting and arc melting methods. The intermediate layers were chosen to assist in alloying between the dissimilar joint materials and to provide an orderly transition in the thermal expansion coefficient of the material across the joint. But in the ground state electronic configuration of iridium, you can see that it has only 7 electrons in d-orbitals. S. El-Genk and M. D.

One class of meteorite, called chondritic (meaning they have a granular structure) still has the original levels of iridium that were present when the solar system was formed.

Set in gold, these nibs shook off the worst ink and pressure could put on them. You'll also find it in specialist parts of industrial machinery. 80 percent of world's tungsten supply is controlled by China. A very thin layer of iridium exists in the Earths crust. Furthermore, China recovers, from domestic sources, approximately 55% of the worlds refined indium.
