![]() is not very liquid so its price can shoot up if there are no sellers," German refiner Heraeus says. Technical problems at South Africa's Anglo American Platinum mining group last year combined with the coronavirus outbreak and lockdowns to hamper operations.Ī decline in demand for platinum has meanwhile had a knock-on effect on iridium which is mined with it. It has a niche role too in helping disinfect water carried as ballast by ships, seen as a key conduit for the transport of invasive plant and animal species around the planet.Ī 2019 accord reached under the auspices of the UN's International Maritime Organization (IMO) requires ship operators to treat ballast water before it is discharged into the sea.Ī troy ounce (31 grammes) of iridium currently costs about $6,000, having tripled over the past four months, largely due to scarcity of supply. Those qualities make it especially sought after for mobile phones, where demand is soaring as 5G technology is rolled out, and in hydrogen fuel cells, potentially a key component in the transition to electric vehicles. When present in compounds, indium exists mostly in the oxidation state III. Like gallium, indium remains in a liquid state over a wide range of temperatures. Indium liquid clings to or wets glass and similar surfaces. Characteristics: Indium is a very soft, silvery-white lustrous metal. Iridium is a rare precious metal with the element symbol Ir, atomic number 77, and an atomic weight of 192.2. Indium is considered to be of low toxicity. Among all metallic elements, iridium is known as the most highly resistant to. Iridium belongs to the transition element of Group VIII of the periodic table. The metal in its raw and pure state is extremely stable and highly dense. Iridium is a transition metal of the platinum family with the symbol Ir and atomic number 77 in the periodic table. Iridium is well suited to several industrial applications "because of its high melting point, hardness and resistance to corrosion," said John Plassard, an analyst with investment house Mirabaud. Iridium is a hard and lustrous member of the platinum group metals which displays high stability in high temperature conditions and in chemical environments. South Africa "accounts for some 80 percent of the six to eight tonnes of iridium mined each year," Vincent Donnen, at the top School of Mines in the eastern French city of Nancy, told AFP. It is extremely hard, with a very high melting point and is resistant to corrosion. Iridium is a chemical element and one of the transition metals on the periodic table. Iridium is a by-product of platinum extraction and is used particularly in the electronics and chemical industries. It is the most corrosion-resistant metal known, and was used in making the standard meter bar of Paris, which is a 90 percent platinum and 10 percent iridium alloy. Because iridium is very hard and brittle, it is hard to machine, form, or work. Hindustan Times - your fastest source for breaking news! Read now. Iridium, a metal of the platinum family, is white (similar to platinum) but with a slight yellowish cast.
