Definitions

  • the invention relates to a heat-resistant platinum material, for many uses in industry and in Laboratory can be used where there are special requirements mechanical, thermal and chemical resistance be required.
  • Such qualities are found in the platinum materials increasingly for high temperature use in the Glass industry, in petrochemicals, in laboratory equipment and in Spark plugs for engines needed.
  • a dispersoid preferably zirconium oxide and yttrium oxide are used.
  • a platinum material is used in US Pat. No. 4,123,263 Glass spinnerets described, the platinum 10 to 40% by weight rhodium, 0.015 to 1.5% by weight zirconium and / or Contains yttrium and 0.001 to 0.5% by weight boron.
  • the Manufacture is carried out using melting metallurgy Intermediate annealing during deformation.
  • This material has an improved creep resistance, Creep rupture strength and resistance to However, grain growth is insufficient.
  • the Rhodium additive which is responsible for the creep resistance of the Material is essentially responsible, considerable Additional costs and is for example when melting optical glasses undesirable because rhodium is in Glass melts in small amounts and dissolves a yellow color caused.
  • DD-PS 157 709 is a platinum metal alloy known, in addition to 0.5 to 5 wt.% Gold and / or nickel 0.01 to 0.5% by weight yttrium, 0.001 to 0.5% by weight calcium and Contains 0.001 to 0.5% by weight boron. This material will also made by melt metallurgy and can also be used in internally oxidized state can be used.
  • This object is achieved by a Platinum material dissolved, in addition to natural Impurities 0.10 to 0.35% by weight of zirconium and / or Zirconium oxide and 0.002 to 0.02% by weight boron and / or Contains boron oxide, the rest of platinum.
  • the material preferably contains 0.15 to 0.25% by weight. Zirconium and / or zirconium oxide and 0.005 to 0.01% by weight Boron and / or boron oxide.
  • zirconium additives to platinum alloys in Amounts of less than 0.5% by weight have a grain-refining effect demonstrate. This goes hand in hand with significantly higher strengths compared to the unalloyed platinum and also applies to the Creep resistance. At higher temperatures is one Coarse grain formation by secondary recrystallization, and as The consequence of this is an early failure due to a slip however inevitable.
