This meter bar was replaced in as a fundamental unit of length see Krypton. Iridium is not attacked by any of the acids nor by aqua regia, but is attacked by molten salts, such as NaCl and NaCN. The specific gravity of iridium is to osmium's specific gravity. Calculations of the densities of iridium and osmium from the space lattices give values of These values may be more reliable than actual physical measurements for determining which element is heavier.
Iridium has several industrial applications, such as the aircraft industry. Its price has surged in recent times due to increased demand from the tech industry. It is believed to have arrived in the same meteor that killed the dinosaurs. Article Sources. Investopedia requires writers to use primary sources to support their work.

Metals Investing in the Metals Markets. Metals What factors affect the price of copper? 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. But because it is so dense and brittle, it is hard to machine, form or work it unless it is heated to extreme temperatures.
Iridium is a member of the platinum family and is white in color with a yellowish hue. It has a density of By comparison, the density of lead is Iridium is not affected by acids, bases, or most other strong chemicals, according to Chemistry Explained. That property makes it useful in making objects that are exposed to such materials. Ingestion: may cause irritation of the digestive tract.
