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 six platinum group 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 costly due to its rarity. Platinum foil has a wide range of applications across industries, including the automobile sector, chemical catalysis, electronics, luxury goods, and research. Its high heat resistance, chemical stability, and surface area make it valuable in multiple applications.
