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 with a (111) orientation, measuring 9-10mm in diameter and 50mm long, stems from platinum's unique properties as a soft, ductile, and malleable silver-white metal. This particular configuration of platinum is optimized for advanced applications, leveraging its inertness and resistance to environmental degradation. Used widely in the production of laboratory and industrial apparatus, thermocouples, resistance thermometers, and electrodes, this crystal form provides precision and reliability. Due to its excellent catalytic properties, it is fundamental in chemical processes such as the synthesis of acetic acid, the production of nitric acid from ammonia, and the manufacture of sulfuric acid. Moreover, its role in controlling automotive emissions is crucial. Originally discovered as a component in various ores and refined from anode sludge in copper-nickel processing, platinum is now indispensable in technologies that require high durability and performance.
