稀金稀金并不是一種單獨(dú)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(jī)械性能。用稀金制做的首飾幾乎可達(dá)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(chǎng)上銷(xiāo)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(gè)貴金屬是2006年才單獨(dú)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(gè)新成員。市面上流行的鈀首飾主要有Pd950和Pd990。①Pd950，要求鈀的含量不得低于950‰，可標(biāo)識(shí)為Pd950或鈀950。②Pd990，要求鈀的含量不得低于990‰，可標(biāo)識(shí)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(chēng)作為“鈀白金首飾”、“鈀鉑金首飾”等含混名稱(chēng)。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?xún)?nèi)的飾品，其重量負(fù)偏差不得大于0．01克。 </p> <p> <br /> </p> <p> <br /> </p><p> 仿真首飾市面上流通的還有少量下列飾品：①包金：就是把黃金打制成極薄的金箔，包在以銅、銀、鋅、鎳等為基體的材料上，加工成各種飾品，這樣既便宜，又給人以黃金相同的感覺(jué)。飾品上往往打24KF、18KF印記。②鍍金：是利用電解原理，在金屬基體表面上鍍上一層金膜，一般厚度為10微米以上，金屬基體多為銅、銀、鋅、鎳或它的合金。其特點(diǎn)是金層極薄，鍍制方便，成本很低，有一定的裝飾效果，但金層易被磨損掉，飾品只有短時(shí)期的輝煌。首飾上常有18KGP，24KGP印記。③亞金：以銅為基體的仿金材料，表面上往往鍍金。④稀金：實(shí)際上不含金，是前幾年出現(xiàn)的一種黃色合金，主要是由銅、鎳等組成的合金，含有少量稀土元素。⑤鈦金：市場(chǎng)上少有出現(xiàn)，也是一種仿金首飾，在基體表面上鍍鈦，生成一種叫TiN的物質(zhì)。另外市場(chǎng)上還出現(xiàn)過(guò)被稱(chēng)作為中國(guó)臺(tái)灣金、泰國(guó)金、鍛壓金的首飾。這些均屬仿金首飾，并不是那些地方產(chǎn)的足金飾品，而是鍍金、包金之類(lèi)的東西。甚至某些旅游區(qū)市場(chǎng)上還有稱(chēng)“寶石金”的首飾，這實(shí)際上也是鍍金、包金制品。

style="text-indent:25px">鈀管純化氫的原理是，在300—500℃下，把待純化的氫通入鈀管的一側(cè)時(shí)，氫被化學(xué)吸附在鈀管壁上并解離成氫原子，氫原子與鈀原子形成合金型氫化物，氫原子占據(jù)金屬晶格中的空隙位置，也稱(chēng)間充型氫化物。在濃度梯度的作用下，氫原子可在鈀管壁中擴(kuò)散，通過(guò)鈀管后重新形成氫分子脫附析出，故可利用鈀管獲得高純氫。雖然鈀對(duì)氫有獨(dú)特的透過(guò)性能，但純鈀的機(jī)械性能差，高溫時(shí)易氧化，再結(jié)晶溫度低，易使鈀管變形和脆化，故不能用純鈀作透過(guò)膜。在鈀中添加適量的IB族和Ⅷ族元素，制成鈀合金，可改善鈀的機(jī)械性能。應(yīng)用的鈀合金中，銀約占20—30%，其他成分（如金等）的含量<5%。氫透過(guò)鈀合金的速率與溫度、膜的厚度及滲透摸兩側(cè)的原料氫和純氫的壓力差（△P）有關(guān)。升高溫度，增大△P及減小膜的厚度，會(huì)使透氫速率增加。但溫度升高，將使?jié)B透膜的抗拉強(qiáng)度降低。因此，鈀管的使用溫度通?？刂圃?50℃以下。某些雜質(zhì)可導(dǎo)致鈀中毒，使透氣性能變壞，甚至可使膜遭到破壞。能引起鈀中毒的物質(zhì)有：汞、砷化物、鹵化物、油蒸氣、含硫和含氨物質(zhì)以及粉塵等。鈀碳回收,做鈀碳回收細(xì)節(jié)很重要哦。廣東正規(guī)海綿鈀現(xiàn)價(jià)</p><p
