Period 5 element electrical contacts and the production of thick-film resistors. A minor application of ruthenium is its use in some platinum alloys. Rhodium is a chemical element that is a rare, silvery-white, hard, and chemically inert transition metal and a member of the platinum group. It has the chemical symbol Rh and atomic number 45. It is composed of only one isotope,Rh. Naturally occurring rhodium is found as the free metal, alloyed with similar metals, and never as a chemical compound. It is one of the rarest precious metals and one of the most costly (gold has since taken over the top
Recycling Rates of Metals report would certainly benefit from greater metals recycling. Among the least-recycled metals are tellurium and gallium, which are used in solar cells, and lithium, which is a key component of the batteries in electric cars. Stocks of these metals are often tied up in old gadgets, such as out-of-date mobile phones, which people often leave in a cupboard and forget about. The report’s authors concluded that appropriate recycling infrastructure should be developed, supported by policy instruments such as research and development, economic incentives and capacity-building activities.
