Suppliers of Platinum and Platinum Alloy Labware
The analytical laboratory is a vital part of all industrial plants and research establishments. The techniques employed therein have developed rapidly in recent years, but the fundamentals upon which many of these techniques are based have remained constant and the majority demand the use of high-purity inert materials. In this category platinum has properties that make it an ideal choice. It has a high degree of chemical inertness and yet can be readily fabricated into a wide variety of articles.
Materials
Metals used for laboratory apparatus must have the following properties
• High temperature strength
• High melting point
• Ductility
• Corrosion resistance
• Oxidation resistance
Platinum and its alloys possess these qualities and is therefore the most widely used metal for analytical laboratory apparatus. Properties of platinum and some common platinum alloys are briefly discussed here.
Platinum Platinum is the best known and least rare of the platinum group metals. Its high melting point, 1773 degrees Celsius, ductility and excellent resistance to chemical attack by acids and fusion mixtures makes it very suitable for laboratory ware. |
Platinum 10% Rhodium This alloy has melting point of 1850 degrees celsius, it has greater hardness and higher strength than other platinum alloy. It is capable of maintaining its shape under the hottest furnace conditions. |
Platinum 5% Gold Universally accepted material of choice for crucible and casting moulds for spectro-graphic analysis by x-ray fluorescence (XRF). The alloy has higher temperature strength than pure platinum and has a “non-wetting” property, which results in easy removal of the sample after fusion and allows for many reproducible assays. |
Platinum Gold Rhodium (87/3/10) This alloy combines the “non-wetting” property of the Pt/Au alloy and the extra strength and durability of Pt/Rh alloys. |
Platinum 3.5% Rhodium The rhodium alloys have higher hardness and high temperature strength making it suitable for more aggressive conditions. |
