Yip said utilisation capacity at its silver salt, palladium salt and rhodium sulphate production lines had exceeded 70 per cent since they opened in January last year, and they were expected to reach 100 per cent by year-end.
Wollaston found two new elements, rhodium and palladium, in an ore found originally in South America.
They were faceted ‘onyx,’ set in sleek gold-toned rhodium : real brazen, but real cool.
It has also shed light on how the rhodium metal surface adsorbs and removes carbon monoxide and nitrogen oxide gases in car exhaust converters.
In this case the relevant market was that for platinum and rhodium , world-wide, and there were only three significant competitors, all based in South Africa.
Actually, the color of white gold is light grey but it is coated with a layer of rhodium .
To give one example, rhodium, a platinum metal, makes up about 2% of the fission products, and the price of rhodium fluctuates between the price of gold and 10 times that.
Neither palladium nor rhodium found much use in early 19th century science and Wollaston was unable to sell his store of the metals, although he attempted to discover applications for them.
Recently, the Grenoble group discovered that uranium rhodium germanium is a ferromagnetic superconductor at ambient pressure.
It employs a chilled mirror of polished rhodium as the primary humidity instrument and infrared optics to control thermoelectric cooling and heating.
