Platinum

铂

Platinum is a grayish-white precious metal. Platinum metal is rare in nature, but the nugget at right was found in the Urals of Russia. Platinum rivals gold in value and is used for jewelry. It is very ductile and can be welded at red heat. It is used in high temperature metal alloys. It has a very small amount of chemical activity and as a result is used for electical contacts under corrosive laboratory conditions.

铂是一种灰白色贵金属。铂在自然界中很稀有,但右边的矿石是在俄罗斯乌拉尔山脉发现的。铂的价值与黄金相当,常用于珠宝。它非常柔软,可以在红热状态下焊接。它用于高温金属合金。由于化学活性非常小,因此在腐蚀性实验室条件下常用于电气连接。

Platinum has important applications as a catalyst for speeding many chemical reactions. Both in the form of platinum sponge and as a fine powder called platinum black it is used for a catalyst in commercial chemical applications. It is used in automobile catalytic converters.

铂作为催化剂,对加速许多化学反应具有重要作用。无论是以铂海绵的形式还是作为一种称为铂黑的细粉末,它都在商业化学应用中用作催化剂。它还用于汽车催化转换器。

Platinum wire is useful for making up standard electrodes for electrochemical cells, and is the substrate of choice for examining the flame colors produced by metal ions since it does not contribute a significant amount of color in the flame.

铂丝常用于制作电化学电池的标准电极,因为它是用于检测金属离子在火焰中产生的颜色的首选基底,因为铂丝本身在火焰中不会显著产生颜色。

One of the most reproducible low temperature thermometers is the platinum resistance thermometer.

一种最可重复的低温温度计是铂电阻温度计。

One platinum containing mineral is sperrylite, PtAs2.

含铂的矿物之一是sperrylite,PtAs₂。
