Definitions
- the invention relates to a heat-resistant platinum material which can be used for many purposes in industry and in the laboratory, where special requirements for mechanical, thermal and chemical resistance are required.
- Zirconium oxide and yttrium oxide are preferably used as dispersoids.
- US Pat. No. 4,123,263 describes a platinum material for glass spinnerets which, in addition to platinum, contains 10 to 40% by weight of rhodium, 0.015 to 1.5% by weight of zirconium and / or yttrium and 0.001 to 0.5% by weight of boron contains.
- the production is carried out by melt metallurgy with intermediate annealing during the deformation. Although this material has improved creep resistance, creep rupture strength and grain growth resistance are inadequate.
- rhodium which is essentially responsible for the creep resistance of the material, entails considerable additional costs and is undesirable, for example, when melting optical glasses, since rhodium dissolves in small amounts in glass melts and causes a yellowing.
- DD-PS 157 709 discloses a platinum metal alloy which, in addition to 0.5 to 5% by weight of gold and / or nickel, 0.01 to 0.5% by weight of yttrium, 0.001 to 0.5% by weight of calcium and 0.001 contains up to 0.5% by weight of boron. This material is also produced by melt metallurgy and can also be used in an internally oxidized state.
- a platinum material which, in addition to natural impurities, contains 0.10 to 0.35% by weight of zirconium and / or zirconium oxide and 0.002 to 0.02% by weight of boron and / or boron oxide, the rest of platinum.
- the material preferably contains 0.15 to 0.25% by weight of zirconium and / or zirconium oxide and 0.005 to 0.01% by weight of boron and / or boron oxide.
- Platinum-zirconium and platinum-boron master alloys are preferably used to manufacture the material in order to be able to adjust the low zirconium and boron contents in the material as precisely as possible.
