贵金属包括金、银和铂族金属铂、钯、铑、铱、锇和钌。直到19世纪,贵金属合金主要用于装饰品、餐具或者宗教用品。随着化学工业的繁荣导致它最早的工业应用。当时对应用作出过贡献的有:Wollastan D(?)bereirer、Matthey、Faraday、Daguerre、Talbot、Claus 和Heraeus。尽管它们作为工业应用的重要性能早已熟知,但直到20世纪才成为关键性的材料,而且是很难找到等效的代用材料。对其性能过去认为最重要的如颜色、光 The precious metals include gold, silver and platinum group metals platinum, palladium, rhodium, iridium, osmium and ruthenium. Until the 19th century, precious metal alloys were mainly used for decorations, tableware or religious items. As the chemical industry’s prosperity led to its earliest industrial applications. At the time, contributions to the app were: Wollastan D (?) Bereirer, Matthey, Faraday, Daguerre, Talbot, Claus and Heraeus. Although well-known for their importance as industrial applications, they did not become a critical material until the 20th century and were difficult to find equivalent substitute materials. For the past, the performance of the past, such as color, light
