隨着珠寶首飾熱的興起,鉑金首飾開始在中國市場上出現。人們對黃金都比較熟悉,但對鉑金的了解卻不多,筆者想在此對其作一些簡單介紹。一、鉑族金屬的種類與特征在礦物分類中,鉑族元素礦物屬自然鉑亚族,包括銥、銠、鈀和鉑的自然元素礦物。它們彼此之間廣泛存在類質同象置換現象,從而形成一系列類質同象混合晶體。同時,其成分中常有鐵、銅、鎳、锇等類質同象混入物,當它們的含量較高時,便構成相應的變種。鉑族元素礦物均為等軸晶系,單晶體極少见,偶而呈立方體或八面體的細小晶粒產出。一般呈不规则粒狀、葡萄狀、樹
With the rapid rise of jewelry, platinum jewelry began to appear in the Chinese market. People are more familiar with gold, but little understanding of platinum, I would like to make some brief introduction here. First, the type and characteristics of platinum group metals In the mineral classification, the platinum group elemental minerals belong to the natural platinum sub-family, including the natural elemental minerals of iridium, rhodium, palladium and platinum. There is a widespread phenomenon of homomorphism displacement between them, thus forming a series of isomorphism mixed crystals. At the same time, its composition often iron, copper, nickel, osmium and other types of homogeneous mixture, when their content is high, they constitute the corresponding varieties. PGM minerals are equiaxed, single crystals are rare, and occasionally was a small cube or octahedral grain output. Generally irregular granule, grape-like, tree
