Description
Platinum was known to native South Americans before the arrival of Columbus and was introduced into Europe around 1750. It is a member of the platinum group metals, lustrous, malleable, and ductile, with an abundance of approximately 0.001 ppm in the earth’s crust. Among the group of six metals (Pt, Pd, Os, Ir, Rh, and Ru), platinum is the most important. It is unaffected by oxygen and water, and is only soluble in aqua regia or fused alkalis.
Platinum foil is a thin film of platinum metal, either pure or in alloy form, available in multiple widths and thicknesses. It is highly inert, corrosion-resistant, silver-white with a shine, and has a wide range of applications. Its rarity makes it costly. Platinum foil is used in the automobile industry, as a catalyst in various industries (e.g., vegetable oil processing, fuel cells), in electronics for heat-resistant contacts, in luxury items, and in research and experimental applications.
