Appearance
Silvery-grey metal
Application
Platinum is a white noble metal that looks very much like metallic silver found in copper ore. The name platinum comes from the Spanish word plata, meaning silver. Platinum compounds were used in the platinum printing process and for toning silver images. Nanoscale platinum powders possess improved reaction rates compared to bulk powders owing to their high surface area. Platinum nanopowders have found use in applications including in fuel cells and oxidation catalysts.

Physical Description
Silvery, whitish-gray, malleable, ductile metal. Mp: 1772°C; bp: 2187°C. Density: 21.45 g cm-3 at room conditions (very dense). Also shipped as a finely divided powder (platinum black), as a sponge, and as particles deposited on a supporting material such as alumina. Has strong catalytic activity in these forms; finely divided platinum can be dangerous to handle in the vicinity of other chemicals on this account. Used platinum catalysts are particularly dangerous and can be explosive.;OtherSolid;Solid;BLACK POWDER.;Silvery, whitish-gray, malleable, ductile metal.;Silvery, whitish-gray, malleable, ductile metal.;
