Can iridium be blue?
Bryce, Durham University, UK, and colleagues have synthesized an iridium complex that can switch between blue, green and yellow luminescent states. These three different forms luminesce in three different colors: one crystalline form in blue, the amorphous form in yellow, and the second crystalline form in green.
What color is iridium on the periodic table?
silver-white
A precious, silver-white metal, iridium is hard and brittle, but it becomes ductile and can be worked at a white heat, from 1,200° to 1,500° C (2,200° to 2,700° F). It is one of the densest terrestrial substances.
Is iridium shiny or dull?
Iridium is a hard, silvery metal. It is almost as unreactive as gold.
What is the texture of iridium?
Iridium is a rare, hard, lustrous, brittle, very dense platinum-like metal.
Does iridium oxidize?
The high-temperature oxidation of iridium metal has only rarely been studied (2 to 7). In the present study the metal losses of polycrystalline iridium in an oxygen atmosphere have been determined gravimetrically at high temperatures of 1500 to 2100°C and low pressures of 0.1 to 100 pascals of oxygen.
How do you identify iridium?
Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, iridium is considered to be the second-densest naturally occurring metal (after osmium) with a density of 22.56 g/cm3 as defined by experimental X-ray crystallography.
What does iridium look like?
Iridium is a member of the platinum family and is white in color with a yellowish hue. It has a density of 22.65 grams per cubic centimeter. By comparison, the density of lead is 11.34 g/cm3 and the density of iron is 7.874 g/cm3.
What is the current price of iridium?
Iridium Price

What are some interesting facts about Iridium?
Facts About Iridium. Iridium is a very hard, brittle and dense metal and is also very rare. Iridium is the most corrosion-resistant element on the Periodic Table of Elements. It also has the highest density of all the elements. Because it resists corrosion, it is used to set standards in weights and measures.
How is iridium used in everyday life?
With osmium, it forms an alloy that is used for tipping pens, and compass bearings. Iridium is used in making crucibles and other equipment that is used at high temperatures. It is also used to make heavy-duty electrical contacts.
What are common uses of iridium?
Uses of iridium Iridium crucibles are used to grow high quality single crystals. These are used in electronics such as computer memory devices and solid state lasers. Iridium is also used in vehicle spark plugs.
What is the origin of iridium?
Iridium was discovered by Smithson Tennant , an English chemist, in London, England in 1803, and it’s name comes from the Latin for iris, the goddess of the rainbow on account of its colored salts. Tennant also discovered osmium .
