Platinum group metals enter glass industry
Monday, 19 July 2010
LONDON, July 18 (Commodity Online): Platinum group metals (PGMs) have been used for many years in the glass industry.
But, now the use of PGMs in glass industry has gone up. According to reports appearing in global media, due to an increase in use of glass in all areas, the use of PGMs in glass making has also gone up.
This will result in a rise in demand for PGMs. According to reports, glass industry will more platinum group metals in the coming years and this may cause a rise in prices of the metals.
Due to their high melting points and superior resistance to corrosion, PGMs are invaluable for protecting manufacturing equipment from attack by molten glass and corrosive vapours.
Although the initial cost of PGMs may be high, they are fully recyclable and, depending on the product, 95 per cent to 98 per cent of the metal can usually be recovered and converted into revenue once the useful life of the component is over. This has helped people use the metal in the industry.
Established products include platinum-rhodium fabrications, which are self-supporting parts or linings usually made of welded sheets of platinum alloyed with between 5 and 20 wt per cent rhodium. Platinum-rhodium alloys with dispersed zirconia particles can give fabrications increased mechanical strength and durability.
The deposition of a thin layer of platinum or platinum with 10 wt per cent rhodium can also be used for ceramic protection in the manufacture of all glass types. Coatings use a lower weight of precious metal than fabrications and are ideal for long runs with limited thermal cycling.
