What Are the Main Uses of the Platinum?

Platinum is silver-white and shiny metal with good ductility, thermal conductivity and conductivity. Sponge platinum is a gray spongy substance with a large specific surface area and strong absorption capacity for gases (especially hydrogen, oxygen and carbon monoxide). Powdered platinum can absorb large amounts of hydrogen. Platinum is chemically inert and stable in air and humidity.

The main uses of platinum are as follows.

In the chemical industry, the platinum net catalyst used in the production of nitric acid has been a significant proportion of platinum consumption; platinum coating lining is an important anticorrosive material for chemical equipment; platinum alloy spinneret is needed to produce synthetic fibers; platinum-based fuel cell has become a widely developed power supply device and has been applied in space.

In electrochemical industry, anodic protection is an electrochemical preservative method, and platinum is the best anode material in various materials. Platinum-plated anode is widely used in the production of chlorine, chlorate, perchlorate, hydrogen chloride and peroxide.

Platinum is mainly used as a catalyst in the petroleum and petrochemical industries. The world's oil industry has a large number of platinum catalytic reforming methods, so the amount of platinum and the iridium in platinum groups is very large.

Platinum is also used to make special industrial equipment and instruments. For example, the industrial production of fiberglass and the melting of high quality chemical glass require large platinum rhodium crucibles. In chemical analysis, platinum crucible vessels and other instruments are important analytical tools.

Also, platinum is an important electronic or electrical material. It is widely used as thermal resistance or resistance thermometers for temperature measuring materials, as well as for precision resistance materials, magnetic and electromagnetic wire materials, electronic tubes and micro-electronic devices. In addition, platinum and precision contact materials are used in the field of weak electricity, and such contacts are widely used in telephone switches, electronics and electrical industries as well as the automotive industry. With the attention of environmental protection, the automobile industry has become a new field of consuming platinum, which has been specially made into a filter neutralizer for automobile equipment to remove harmful impurities from tail gas.

Platinum is also used to make jet engine fuel nozzles, a high temperature protective coating for the front cone of the spacecraft, and the separation of production and plutonium for heavy water. Recently, a platinum catalyst has been successfully used to solve air pollution caused by urban traffic and factory pollution.
