The metal was used by pre-Columbian Americans near Ecuador to produce objects made of a white gold-platinum alloy. Italian writer Julius Caesar Scaliger described it in the 1500s as an unknown noble metal found between Darien and Mexico, "which no fire has yet been able to liquefy." Industr...
PLATINUM GOLD ALLOY BASED ON GOLDThe invention relates to alloys based on gold intended for jewellery industry. An alloy contains, w/w: platinum 22.3 and gold 77.7. The proposed alloy has improved mechanical properties and original colour spectrum.YAKOVLEV MAKSYM VIKTOROVYCH...
White gold is an alloy of gold and has the same symbol as gold Au. ColorPlatinum is a natural white metal, while white gold is given its color artificially by alloying gold with silver or palladium and by adding rhodium plating to it. Nickel used to be a very popular metal used to ...
studied the effect of Zr content on the microstructure and properties of the dispersion strengthened Pt20Rh alloy, and found that the existence of ZrO2 particles makes the alloy have a more stable grain structure under high temperature service condition. With the increase of Zr content, its room...

The work function of the gold-rich alloy is lower than that of gold or that of platinum. These results are completely analogous to those found previously for the Cu Ni system. The previously predicted dependence of surface composition on the surrounding gas atmosphere has been experimentally ...
of these is the most important, with around 80% of disks now having Pt. Modern PCs have a hard disk drive with several disks, produced from either Al or high-quality glass coated with several layers, one of which is a Co-Pt alloy with magnetic properties in which information is stored....
