Zusammenfassung:Methods for reducing the evaporation rate of platinum and Pt alloys upon their use at high temperatures >1,200° C. in an oxidizing atmosphere include the steps: (A) providing a component made of platinum or a platinum alloy; (B) wrapping the outer surface of the component with a flexible bandage having open porosity and provided with an oxide ceramic material and/or a glass-forming material; (C) using the component at operating temperatures >1,200° C. Methods for scavenging noble metal oxides evaporating or sublimating from the surface of platinum or Pt alloys include: (A) providing a component made of platinum or a platinum alloy; (B) wrapping the outer surface of the component with a flexible bandage having open porosity; and (C) using the component at operating temperatures >1,200° C. Correspondingly wrapped components are also provided.
