金屬在人類社會發展中扮演著重要的角色,而其中一些金屬因其稀有性和獨特性而被視為珍貴品。以下是十大最貴金屬的排名以及它們在各個領域中的應用。

1. 銥(IriDIum)

銥是地球上最稀有、最難提取的元素之一,也是目前已知最重的元素。由於其抗腐蝕性和高熔點,銥主要用於製造高溫裝置、火箭噴嘴和電觸頭等。

2. 鉑(Platinum)

鉑常被用作首飾材料,但更廣泛地應用於汽車催化轉化器、醫療設備和電子產品中。它還被認為是世界上最珍貴的工業金屬之一。

3. 金(Gold)

黃金自古以來就被視為珍貴物品,在首飾製造、貨幣生產以及投資領域廣泛使用。此外,黃金還在航天器件和電子產品中發揮著關鍵作用。

4. 鈀(Palladium)

鈀主要用於汽車催化轉化器、電子設備和珠寶製造。近年來,鈀價格不斷攀升,並成為市場上備受追捧的投資標的之一。

<7.Iron(Fe)

Iron is a chemical element with symbol Fe and atomic number 26.It is a metal that belongs to the first transition series and group 8 of the periodic table.It is by mass the most common element on Earth, forming much of Earth's outer and innercore.

<8.Titanium(Ti)

Titanium is a chemical element with symbol Ti and atomic number 22.It is a lustrous transition metal with a silver color, low density, and high strength.Titanium is resistant to corrosion in sea water.

<9.Silver(Ag)

Silver has long been valued as a precious metal.Silver metal is used in many bullion coins,sometimes alongside gold:while it was formerly used for coins also,the amount of bullion coins minted over time decreased to near zero.

<10.Copper(Cu)

Copper does not react with water,but it does slowly react with atmospheric oxygen to form acarbonat eohydroxide.Copper can be combined easilywith other metalsto make alloys.The following are someofthe morecommonalloys:coppertin,zinc,silicon,nickel,and aluminum.Bronzeis an alloymade from copperand tin,and brassis an alloy made from copperand zinc.
