鉑金白金是鉑（Pt）的別稱或俗稱，是一種比白金首飾黃金價值更高的貴金屬。密度21.43g/cm3，熔點1773℃，均高于黃金，但產(chǎn)量*為黃金的1/20，是一種化學(xué)穩(wěn)定性更好，比黃金更稀少、更名貴、更具有保值增值性的貴金屬。近幾年鉑首飾十分流行，特別是鉑鑲嵌首飾更是受人們喜愛。 </p> <p> <br /> </p> <p> 金“K白金”并不是K鉑金，而是一種白色的K黃金（英文名稱為White Gold，即白色金），而白金（鉑）英文名稱為Platinum。市面上銷售的所謂18K白金首飾實際上是白色的18K黃金飾品，它保證其中黃金含量不低于750‰，其余的是銅、鋅、鎳、銀、鈀、銠等。因成分比例不同，還可產(chǎn)生不同的顏色，即18K彩色金首飾。為了防止誤導(dǎo)消費者，標(biāo)準(zhǔn)規(guī)定不得使用“K白金”或“白K金”這個名稱，而只能標(biāo)識為“白色18K黃金”或“白色18K金”，或直接標(biāo)識為“18K金”。 </p> <p> <br /> </p><p style="text-indent:25px">首飾變白發(fā)黑的原因當(dāng)足金首飾接觸到汞（**）時，會很快生成一種白色的汞金化合物附著在首飾表面，但當(dāng)將發(fā)白處放在酒精燈上灼燒時，白色又會很快消失。醫(yī)務(wù)工作者因經(jīng)常與血壓表、體溫表接觸，佩戴足金首飾時，常常會遇到這種現(xiàn)象。足銀首飾遇到硫（S），會生成一種黑色的硫化銀物質(zhì)，使銀首飾表面發(fā)黑。如戴銀首飾的人用硫磺香皂沐浴時，就有可能會出現(xiàn)銀首飾變黑的現(xiàn)象，因此要注意保養(yǎng)。蘇州德誠貴金屬回收利用有限公司歡迎您!鈀對氫有獨特的透過性能。</p><div
