Nickel, platinum, and palladium are typically silvery-white transition metals, and can also be readily obtained in powdered form. [12] They are hard, have a high luster , and are highly ductile . Group 10 elements are resistant to tarnish ( oxidation ) at STP , are refractory , and have high melting and boiling points.
In addition, gold, copper, iron, mercury, tin, and lead may occur in alloys of this group. [8] As with gold, salts and other compounds of the platinum group metals are rare; native platinum and related metals and alloys are the predominant minerals bearing these metals.
Naturally occurring platinum and platinum-rich alloys were known by pre-Columbian Americans for many years. [5] However, even though the metal was used by pre-Columbian peoples, the first European reference to platinum appears in 1557 in the writings of the Italian humanist Julius Caesar Scaliger (1484–1558) as a description of a mysterious metal found in Central American mines between ...
In 1969, an alloy of 77.5% palladium, 6% copper, and 16.5% silicon was found to have critical cooling rate between 100 and 1000 K/s. In 1976, Liebermann and Graham developed a method of manufacturing thin ribbons of amorphous metal on a supercooled fast-spinning wheel. [6] This was an alloy of iron, nickel, and boron.
