Stabilized platinum (Pt GSP) is a material that has been known for many years, but until now has only been used for special purposes.
Pure platinum is the basic material choice, offering a relatively low price, on the other hand it is quite soft and vulnerable to grain coarsening after prolonged high temperature exposure. Alloying with rhodium increases the material hardness and slows down grain growth, but can be significantly more expensive. Grain Stabilized Platinum (GSP) is a powder-metallurgy material alternative with introduced dispersed zirconia oxide nanoparticles in the platinum matrix.
This yields superior creep resistance and long grain-boundary path for potential “platinum-poison” contaminant, without costly alloying elements. It is essentially pure platinum, where the crystalline lattice of the metal is stabilized by the addition of another element (e.g. zirconium) which causes the crystalline structure of the metal to strengthen. The material thus acquires better mechanical properties and a longer service life than the original pure metal.
Areas of application of stabilized platinum
Laboratory equipment – the ideal use of stabilized platinum is laboratory equipment and tools, such as cups, bowls, lids, spoons, shovels, spatulas, etc. This means products that are manufactured by metal stamping, without the need for welded joints. Safina offers a full range of dimensional variants of these products, which are listed in our catalog available on the website.
Tubes, thimbles, annulus – longitudinal welded tubes, produced by twisting sheet metal and welding it thimbles made of welded tubes with a flange and a round or flat bottom
Both of these products are offered in various dimensional options, according to the customer’s needs. The limitation is the minimum material thickness of 0.18 mm, small diameters below approx. 6-8 mm
Products for glass industry – these are spare parts for technology that come into contact with molten glass and must be resistant to high temperatures over 1200 ° C.
These are, for example, the following products:
- spouts
- outlet devices
- homogenizers
- crucibles
- stirrers
- bushings
- etc.
All these products are manufactured according to the specifications given by the technical documentation and drawings.
