Palladium's uses in health eare

摘要

Palladium is a silver-white ductile metal, in the platinum group, with an atomic number of 46. It was discovered in 1803 by the English chemist William. Hyde Wollaston during a study of platinum ore. Russia and South Africa produce 93 per cent of the world's palladium, with smaller quantities mined in Canada and the US. Natural palladium contains six stable isotopes, with a further 25 that are radioactive. Palladium alloys are used extensively in dentistry, electrical circuitry, watch-making and the jewellery industry. It is prized for its catalytic properties and is an essential comoonent in the catalvtic convertors of motor vehicles.
