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 Platinum single crystal, with dimensions of 9-10mm in diameter and 50mm in length, and a (100) orientation, serves a versatile and crucial role in both scientific and industrial applications. Its primary purpose lies in its unique structural and chemical properties, which make it exceptionally valuable for the fabrication of high-precision laboratory equipment such as thermocouples and platinum resistance thermometers. These devices leverage platinum's stable electrical conductivity and thermal properties. Additionally, this platinum crystal can be utilized in the creation of acid-resistant containers and electrodes, significantly benefitting industries that require robust and reliable tools. Its catalytic abilities are pivotal in various chemical processes, including the manufacture of acetic and sulfuric acids and in emission control systems. While its applications extend to fields like dentistry, jewelry, and electroplating, its core utility remains deeply rooted in its role as a catalyst and a critical material for scientific instruments and industrial apparatuses.
