Platinum Foil, Purity 99.95%, Thickness: 1mm, 10×10 cm

Platinum was known to native South Americans before the arrival of Columbus and was introduced into Europe around 1750.

Platinum is a member of the platinum group metals and is lustrous, malleable, and ductile; it has an abundance of approximately 0.001 ppm in the earth’s crust. Of the group of six metals (Pt, Pd, Os, Ir, Rh, and Ru), it 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, which is available in multiple widths and thicknesses. It has the inertness and remarkable feature of resistance to corrosion with increased surface area as it is in the form of a foil. It is usually silver-white with a shine. It is costly as it is a rare metal. It has a very wide range of applications.

Its use in the automobile industry is well known. It’s used as a catalyst in several industries such as vegetable oil, fuel cells, etc. is common. It is also used as a standard to many measures as its resistant to corrosion. It is also used in electronics for its high resistance to heat with melting points of 1768^oC. It is being utilized by watches and mobile industries and also by jewelers to make luxury items. Apart from these, it is widely being used for experiments and researches and is supposed to have a lot of potential in the future.

Platinum foil is used as a matrix or support structure for the build-up of all-ceramic restorations. Platinum foil does not readily oxidize, and therefore will not bond to the porcelain. In most cases, the platinum foil is removed and scrapped once the porcelain work is complete. However, with some jacket crown techniques, the platinum foil is tin-plated and bonded directly to the porcelain. With these techniques, called “platinum reinforced jacket crowns”, the platinum foil remains in the crown and is cemented to the prep. There are no techniques for platinum reinforced veneers; with veneers, the platinum foil is always removed.
