Chemical Properties

40-200 Mesh Powder
Storage & Sensitivity
Ambient temperatures.
Soluble in aqua regia. Insoluble in water, mineral acids and organic acids.


Platinum is a catalyst used for hydrogenation of alkenes, alkynes, nitro groups. It is also used for hydrogenolysis of cyclopropanes, catalyzes oxidation of alcohols and reduction reactions. It is well-suited for making fine jewelry. Platinum and its alloys are used in surgical tools, laboratory utensils, electrical resistance wires, and electrical contact points. It is used in the catalytic converter, an optional component of the gasoline-fuelled automobile exhaust system. It is also used in the chemical, electrical, glass and aircraft industries. The glass industry uses platinum for optical fibers and liquid crystal display glass, especially for laptops.


Incompatible with interhalogens, halogens, oxidizing agents and hydrogen fluoride. Keep container tightly sealed. Store in cool, dry conditions in well sealed containers.
