Rhodium
“Rhodium
is a silver-white metallic element, is highly resistant to corrosion, and is
extremely reflective. It is used as a finish for jewelry, mirrors, and search
lights. It is also used in electric connections and is alloyed with platinum
for aircraft turbine engines. Another use is manufacturing of nitric acid and
used in hydrogenation of organic compounds. Rhodium usage is dominated by
automotive catalyst applications where it is used together with platinum and
palladium to control exhaust emissions.
South
Africa is the major source, accounting for almost 60% of the world’s rhodium
supply Russia is the second largest producer, although its sales are, as with
the other PGMs, volatile and subject to political intervention.”
