Now and in the future, the unique qualities of platinum
group metals (PGMs) make them crucial to the operation of many
technological innovations and bring us closer to the day when,
thanks to PGMs science fiction becomes science fact.
Computers
The single largest electronic application for platinum is in computer hard
disks, often alloyed with cobalt to improve its magnetism and storage capabilities.
Platinum-cobalt coatings are now crucial in the hard disks of virtually
all computers manufactured today - at least 90% by the start of 2001. This
allows for a greater data storage density and has thus enabled manufacturers
to reduce the number of disks in each hard drive.
PGMs are also key to the efficiency and reliability of components crucial
to the operation of computers (and other electronic devices) such as ceramic
capacitors and electrodes on which platinum, palladium, rhodium and iridium
are coated to boost conductivity and durability.
Telecommunications
As well as their role in all electronic devices, PGMs may, in the future,
offer a new leap forward in mobile telecommunications technology. Compact
and flat fuel cells employing PGMs and PGM alloys as a catalyst are being
developed and may in the future provide a more reliable and efficient source
of power for mobile telephone handsets, eliminating the need for regular
electrical re-charging. |
