CAS 7440-06-4PubChem CID 23939

Platinum

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. — CAMEO Chemicals
