I love you, too, but my husband is a chemical engineer, so I trust my husband on this issue.<g>

>>Electronics

The prime use is in electronics. Our age of high
technology finds it indispensable in everything
from pocket calculators to computers, washing machines to television and
missiles to spacecraft. The rocket engines of American space shuttles are
lined with gold brazing alloys to reflect heat, and the lunar modules of the
Apollo programme that put men on the moon were shrouded with gold
foil acting as a radiation shield. More commonly, the humble touch
telephone in your home typically contains 33 gold-plated contacts.
The plating of such contacts in switches, relays and connectors is the
major application of gold in electronics. Contacts are electroplated with a
very thin film of gold using gold potassium cyanide (GPC), often called
plating salts. This touch of gold on a contact ensures rapid dissipation of
heat and guarantees freedom from oxidation or tarnishing at extreme low
or high temperature, thus providing an atomically clean metal surface with
an electrical contact resistance close to zero. Not surprisingly "nothing is
as good as gold" to provide total reliability, whether out in space or in the
home.<<
