![]() ![]() Iridium spark plugs are wear-resistant, with an amazing consistency by natural orchestration. Iridium has the potential of lasting for a long time, which helps to maintain the longevity of the spark plug so that you don’t always have to replace your car’s spark plugs. However, because the Earth’s core is rich in iridium, other scientists argue that iridium came from volcanic origin. By Michelle Houchins, Iridium Diversity & Inclusion Council member and Engineer. Iridium is an incredible metal that comes with lots of great features. Iridium is a chemical element of the periodic table with chemical symbol Ir and atomic number 77 with an atomic weight of 192.217 u and is classed as transition metal and is part of group 9 (cobalt group). By 2011, the demand for this metal was for 194,000 ounces and that was 27 times what it was back in 2009. The metal become highly valuable as flat screen TVs and tablets became more popular. Many scientists believe that iridium originated from an asteroid or comet that was the cause of the extinction of the dinosaurs. It was due to the increasing popularity of LED screens. This time period that marks the temporal border between the Cretaceous and Tertiary eras in geological time was identified by a thin layer of clay that contained an abnormally high level of iridium. The KT extinction event was a period over 65 billion years ago that marked the extinction of many forms of life such as, most popularly, the dinosaurs. Iridium salts vary widely in color, which is why iridium was named after the Latin word for rainbow: iris. One key player in this market is Johnson Matthey Plc, a multinational chemicals and precious metals company. ![]() The global iridium market is influenced by a variety of factors that can impact the metal’s price. Market Factors Affecting Iridium’s Price. Iridium is used as a hardening agent for platinum and for making tools that are exposed to high temperatures, like crucibles. Iridium-platinum alloys are particularly prized for their resistance to wear and tarnishing. ![]()
