| plating | 1. The art or process of covering anything with a plate or plates, or with metal, particularly of overlaying a base or dull metal with a thin plate of precious or bright metal, as by mechanical means or by electromagnetic deposition. 2. A thin coating of metal laid upon another metal. 3. A coating or defensive armor of metal (usually steel) plates. Source: Websters Dictionary (01 Mar 1998) |

| platinum | <chemistry> A metallic element, intermediate in value between silver and gold, occurring native or alloyed with other metals, also as the platinum arsenide (sperrylite). It is heavy tin-white metal which is ductile and malleable, but very infusible, and characterised by its resistance to strong chemical reagents. It is used for crucibles, for stills for sulphuric acid, rarely for coin, and in the form of foil and wire for many purposes. Specific gravity 21.5. Atomic weight 194.3. Symbol Pt. Formerly called platina. <chemistry> Platinum black, a soft, dull black powder, consisting of finely divided metallic platinum obtained by reduction and precipitation from its solutions. It absorbs oxygen to a high degree, and is employed as an oxidizer. <physics> Platinum lamp, metallic platinum in a gray, porous, spongy form, obtained by reducing the double chloride of platinum and ammonium. It absorbs oxygen, hydrogen, and certain other gases, to a high degree, and is employed as an agent in oxidizing. Origin: NL, fr. Sp. Platina, from plata silver, LL. Plata a thin plate of metal. See Plate, and cf. Platina. Source: Websters Dictionary (01 Mar 1998) |
| platinum compounds | Inorganic compounds which contain platinum as the central atom. (12 Dec 1998) |
| platinum foil | Pure platinum rolled into extremely thin sheets; its high fusing point makes it suitable as a matrix for various soldering procedures in dentistry, and also suitable for providing internal form to porcelain restorations during their fabrication. (05 Mar 2000) |
