Platinum, Platinum/Rhodium and Platinum/Gold alloy Crucible and mould XRF Analysis

Platinum and its alloy possess the following properties to use for laboratory apparatus:

• Higher strength
• High melting point

• Ductility
• Corrosion resistance

• Oxidation resistance

And therefore, Platinum and its alloy are widely used as a analytical laboratory apparatus. The properties of Platinum and its alloys are summarized as under:

Platinum / 10% RhodiumThis Platinum group metal alloy melting point as high as 1850 degree Celsius. This alloy has greater hardness and higher strength

Platinum / 5% GoldThis alloy universally accepted for Crucibles and casting moulds for spectro-graphics analysis by x-ray fluorescence (XRF). This alloy has property of higher temperature strength than pure Platinum and has “non-wetting” property for easy removal of the sample after fusion and allows many reproducible assays.
