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.

Application
The purpose of the Platinum single crystal disc, 10mm in diameter and 1-2mm thick, with (111) orientation, is to provide an ideal surface for scientific and industrial applications where platinum's unique catalytic properties, high stability, and corrosion resistance are required. This product serves as a reliable material in fields such as electronics, chemical processing, and advanced materials research, paralleling the functionality of tantalum in its capacity as a catalyst and its resistance to chemical reactions, thereby ensuring durability and efficiency in demanding environments.
Color/Form
