The main role of iridium rhodium, iridium rhodium contrast.

Among the chemical elements, iridium (Ir) and rhodium (Rh) belong to the platinum group and have unique properties and a wide range of applications. Let's take a look at the main roles of these two metals and compare them.

The main role of iridium
Catalyst: Iridium is commonly used as a catalyst, especially in the chemical industry in the process of hydrogen oxidation reaction, hydrogen production plays an important role. In oil refining, for example, iridium catalysts can help convert hydrogen sulfide into sulfur, purifying the fuel.
Resistors: Because iridium has a very high melting point and good corrosion resistance, resistors made of iridium are widely used in high temperature environments, such as rocket engines and nuclear reactors.
Jewelry: Because iridium has a silver-white appearance and good corrosion resistance, iridium alloys are often used to make high-end jewelry, such as platinum as one of the alloy components.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

The main role of rhodium
Catalyst: Rhodium is an excellent catalyst, often used in three-way catalytic converters in automotive exhaust treatment systems to convert harmful gases into more environmentally friendly gases, such as carbon monoxide to carbon dioxide.
Electroplating: Rhodium plays an important role in the electroplating industry, which can provide excellent protective coating for the metal surface, increase its corrosion resistance and beauty, and is often used in the production of jewelry, watches and other items.
Medical devices: Due to rhodium's good biocompatibility, rhodium alloys are often used to make medical devices, such as cardiac pacemakers and stents, for the treatment of cardiovascular diseases.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Iridium versus rhodium
Iridium is mainly used in the field of catalysts and high-temperature resistors, while rhodium is widely used in the field of catalysts, electroplating and medical devices, and has more uses.
Properties Difference: Iridium has a higher melting point and better corrosion resistance, suitable for use in extreme conditions, while rhodium is more biocompatible and more suitable for medical device manufacturing.
After comparing the main role of iridium and rhodium, we can see that although they belong to the platinum group elements, they have their own different characteristics and advantages in practical applications. For scientists and engineers, an in-depth understanding of the properties of these two precious metals helps to better select suitable materials and play to their advantages in different fields.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling- 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-
