Specification
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 in the (110) orientation is to serve as a high-precision substrate for advanced scientific applications. This disc is carefully crafted to take advantage of the unique physical and chemical properties of platinum, making it ideal for use in catalyst support, electronic devices, and corrosion-resistant tools. Its distinct orientation and single crystal structure allow for controlled interactions at the atomic level, facilitating the development and enhancement of next-generation materials and technologies. Such platinum discs are crucial in research and industrial settings where reliability and precision are paramount.
