摘要：

铑和铱是两种稀有的铂系元素，性质十分相似。本文以第三人称拟人化的口吻，通过游戏闯关的形式对两种单质的沸点、反射率、弹性模量、催化活性和化学稳定性等物理化学性质进行介绍。还穿插讲述了其氧化物和卤化物的性质以及在电镀层、汽车尾气催化转化器、热电偶等领域的应用。

关键词: 铑, 铱, 铱铑合金

Abstract:

Rhodium and iridium are two rare elements of the platinum family, and they have very similar properties. In a third-person personification, their unique physical and chemical properties, such as boiling point, reflectivity, elastic modulus, catalytic activity, and chemical stability have been introduced by designing a game of challenges. Additionally, the properties of their oxides and halides are also included, especially their applications in electroplating, automobile tail gas catalytic converters, thermocouple manufacturing.

Key words: Rhodium, Iridium, Iridium-rhodium alloy
