稀金稀金并不是一種單獨的金屬，而是一些稀有金屬的合金。由于稀金具有某些可與黃金相媲美的特性，如象黃金一樣的色澤，同黃金一樣的化學(xué)穩(wěn)定性和相似的機械性能。用稀金制做的首飾幾乎可達到與金首飾亂真的程度。金銀鉑鈀依據(jù)GB11887－2002《首飾貴金屬純度的規(guī)定及命名方法》，市場上銷售的貴金屬首飾可分為金首飾、銀首飾、鉑首飾和鈀首飾4種。鈀首飾鈀鈀這個貴金屬是2006年才單獨被制作為首飾的，以往都是在鉑首飾中作為摻合物，是貴金屬首飾家族中又一個新成員。市面上流行的鈀首飾主要有Pd950和Pd990，湖北硝酸鈀報價。①Pd950，要求鈀的含量不得低于950‰，可標(biāo)識為Pd950或鈀950。②Pd990，湖北硝酸鈀報價，要求鈀的含量不得低于990‰，湖北硝酸鈀報價，可標(biāo)識為Pd990或鈀990。含鈀量不低于750‰ 和500‰的鈀首飾主要用于鑲嵌。不允許將鈀首飾稱作為“鈀白金首飾”、“鈀鉑金首飾”等含混名稱。另外，標(biāo)準(zhǔn)規(guī)定還要求，貴金屬首飾的重量要保留兩位小數(shù)，單件重量在100克以內(nèi)的飾品，其重量負偏差不得大于0．01克。 </p> <p> <br /> </p> <p> <br /> 為什么要進行貴金屬回收？湖北硝酸鈀報價</p><div
