Jul 11, 2019· Platinum Vs. Gold. Platinum is a naturally occurring chemical element that is actually about 30 times rarer than gold, according to Jenny Luker, president of Platinum Guild International USA (PGI), a marketing organization for the platinum jewelry industry. "If all the platinum ever mined were melted and poured into an Olympic-sized pool, the platinum would …
The number of ligands bound to the transition metal ion is called the coordination number. Although coordination complexes are particularly important in the chemistry of the transition metals, some main group elements also form complexes. Aluminum, tin, and lead, for example, form complexes such as the AlF 63-, SnCl 42- and PbI 42- ions.
Properties of Platinum. Physically, platinum is a soft, lustrous, silver-coloured metal. It is highly dense (21.5 g/cc), malleable and ductile (there is an ongoing debate if it is the most ductile). It is also highly corrosion resistant and has a high boiling point ( around 1700 degrees Celsius or 3220 degrees Fahrenheit).
Scope. 1.1 This specification covers an 85 % platinum—15 % iridium alloy, and a 90 % platinum—10 % iridium alloy, in the form of rod, wire, strip, and sheet material for electrical contacts. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be ...
