Herstellung von Fasern aus Platin oder Palladium oder Legierungen auf Platin- oder Palladiumbasis und von Vliesen oder Netzen daraus

The invention relates to a method for producing fibers made of platinum, palladium, or alloys based on Pt or Pd from a melt by gas atomizing, wherein the viscosity of the melt is adjusted by alloying boron so that fibers, not powder, are created by atomizing. The fibers thus created can be sintered...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing fibers made of platinum, palladium, or alloys based on Pt or Pd from a melt by gas atomizing, wherein the viscosity of the melt is adjusted by alloying boron so that fibers, not powder, are created by atomizing. The fibers thus created can be sintered into non-woven mats or meshes. The boron can be thermally removed as an oxide. The method is particularly suitable for fibers made of PtRh alloys.
