Platinum
Wire, Foil Rod and Pieces
Purity Range: 99% to 99.99%
Platinum is a ductile, bright silvery white metal, malleable and a member of group 10 of the periodic table of elements. It has the third highest density, behind osmium and iridium. Platinum is a shiny silver-grey metal that is malleable and ductile. Malleable means capable of being hammered into thin sheets. Platinum can be hammered into a thin sheet of no more than 100 atoms thick, thinner than aluminum foil. Platinum is very ductile so the metal can be stretched into thin wires.

Platinum wire is not affected by air and water, but will dissolve in regular hot water, in hot concentrated phosphoric and sulfuric acids, and in molten alkali. It is as resistant as gold to corrosion and tarnish. Platinum wire will not oxidize in the air, no matter how strongly it is heated.
Platinum foils are used in various laboratory processes. Also, Platinum is used in dental veneers and as a matrix or support structure for the build-up of all-ceramic restorations.
Platinum pieces and pellets are used in deposition processes, Platinum Sputtering Targets are used in the coating and electronics/computer industries and Platinum is also made in various lab-wares such as crucibles, trays, lids and trays.
