Gold-platinum alloys

Gold and gold-based alloys ate used for corrosion-resistant equipment. Gold—platinum alloys, 75 Au-25 Pt or 84 Au-15 Pt-1 Rh, ate used as cmcible material for many molten salts (98). Spinnerets for rayon manufacture ate based on the Au—Pt system which exhibits a broad miscibility gap in the soHd state so that the alloys can be age-hardened. Spinneret alloys contain 30—40% or mote platinum modified by small additions of usually rhodium (99). Either gold or gold—platinum alloys ate used in mpture disks for service with corrosive gases (100). [Pg.384]

Jets for continuous filament textile yarn are typically 1-cm-diameter gold-platinum alloy structures with 20-500 holes of 50-200-/am diameter. Tire yarn jets are also 1 cm in diameter but typically use 1000-2000 holes to give the required balance of filament and yarn denier. Staple fiber jets can have as many as 70,000 holes and can be made from a single dome of alloy or from clusters of the smaller textile or tire yarn jets. The precious metal alloy is one of the few materials that can resist the harsh chemical environment of a rayon machine and yet be ductile enough to be perforated with precision. Glass jets have been used for filament production, and tantalum metal is a low cost but less durable alternative to gold-platinum. [Pg.1163]
