Platinum is an extremely resistant material. But there are applications which exceed its physical and chemical limits. FKS platinum (FKS=”feinkornstabilisiert”) was developed to expand this range of applications. An addition of zirconium oxide hardens platinum, contribute to grain refining and reinforce the structure of the Pt alloys.

Dispersion-hardened platinum has been accepted for applications both in the glass industry and the
laboratory. FKS platinum and FKS platinum alloys feature a number of outstanding characteristics
which benefit users:

• No structural change during annealing (recrystallization) > better mechanical resistance
• Increase in tensile strength and yield strength as much as two-fold
• Increase in long time rupture strength > appliances made of FKS Pt can be used up to three times longer than those made of normal Pt alloys
• Increase of the max. use temperatures by as much as 20 % in comparison to commonly used alloys
• Higher degree of chemical resistance

These materials are available:

Ögussa supplies all crucibles and dishes, especially for X-ray fluorescence analysis, made both of traditional Pt alloys as well as of FKS Pt. This gives users the option of selecting the variant which is best for them.
