本文评述了贵金属的热电性能。金、银的绝对热电势率为正;铂族金属为负;钯、铂等过渡族元素与银、金的合金存在有负的极大值;银、金中含有极少量的铁磁性金属(如铁、钴、镍)杂质,在低温下将出现巨大的负的热电势率。文中还系统介绍了铂铑系、铱铑系和钯基合金等高温热电偶材料以及金铁、金钴等低温热电偶材料。 This article reviews the thermoelectric properties of precious metals. The absolute thermoelectric power of gold and silver is positive; the platinum group metal is negative; the transitional elements of palladium and platinum have negative maxima with silver and gold alloys; the silver and gold contain very small amounts of ferromagnetic metals Such as iron, cobalt, nickel) impurities, at low temperatures will be a huge negative thermoelectric power. The article also systematically introduces the high temperature thermocouple materials such as platinum and rhodium, iridium and rhodium and palladium-based alloys as well as the low-temperature thermocouple materials such as gold and iron, gold and cobalt.
