What Does Indium React With

Brief introduction of indium applications:
Indium has good ductility, plasticity, low melting point, high boiling point, low resistance, corrosion resistance and other excellent properties, and has good conductivity and light penetration, is widely used in aerospace, radio and electronic industry, medical, defense, high-tech, energy and other areas.

The production of ITO target is the main consumption of indium, accounted for 70% of global indium consumption; the second is semiconductor field, accounted for 12% of global consumption.

ITO target
Indium ingot has better light penetration and electrical conductivity, the glassy compound of high purity indium oxide and tin oxide (ITO) is used to make transparent conductive electrode in the plasma TV and LCD TV screen industry, is also used as a sensitive element of certain gas measurement. 70% of global indium consumption is used to produce ITO targets.application

Electronics, semiconductors and radio
Indium has high boiling point, low resistance and corrosion resistance. It is widely used in the field of electronic, semiconductor and radio industries. A large proportion of indium is used in the manufacture of semiconducting materials. In the radio and electronics industries, indium is used to make special contact devices that are prepared by mixing indium and silver oxides.


Applications of indium in solders and alloys
The strength and improve the ductility, wear resistance and anti corrosion properties of many alloy can be improved after adding a small amount of indium alloy, which also known as "a indium alloy vitamin", "wonderful effect of indium".

Indium alloys can be used as solar cells. CIGS thin film solar cell has the advantages of low production cost, low pollution and no recession, weak light performance, photoelectric conversion efficiency is the top in a variety of thin film solar cell, close to the crystal silicon solar battery, and the cost is 1/3 of crystalline silicon solar cells. In addition, the battery has a soft, uniform black appearance, is the ideal place which has high demand for the appearance, such as large buildings glass curtain wall in the modern high-rise buildings and other fields.

Because of its ductility, plasticity, vapor depression, and adhesion to a variety of materials, it is widely used as a gasket and lining material in high-altitude instruments and aerospace equipment. Indium foil is often used as an ultrasonic linear block contactor.


In the atomic energy industry, indium is used as an indicator for making neutrons. Indium alloy is used in the manufacture of control rods in nuclear reactors. Indium is also a good material for making neutron detectors and comparable to metal gallium.

The initial application of indium is used to manufacture industrial bearings in the industry, and its use in this respect has continued so far. The surface of the bearing is plated with indium, and the service life of the bearing is more than 5 times longer than that of the ordinary coating. The alloys of indium and gallium can be lubricated by sliding elements and are therefore used in electric vacuum instruments.

Indium is easy to form a solid coating on the metal surface, and has good corrosion resistance, especially to prevent alkaline solution from corrosion. The coating of indium not only has bright color, but also is easy to polish. In addition to pure indium coatings, alloys such as indium and zinc can also be used as coatings. Indium coatings are also used in decorative processes. If the surface of a variety of mirrors and reflectors is plated with indium, the reflectivity will be greatly enhanced and resistant to seawater erosion, so the mirror is commonly used in marine ships. In addition, a bronze wire mesh with an indium plated surface can be used to remove mercury vapor from a vacuum instrument.

Because of the low melting point of indium, so it can produce a variety of fusible alloy. The range of indium alloy is 47~122 degrees; used to make a wide variety of fuses and thermostats.

The more promising application of indium is in the field of stomatology. Alloys are used as false teeth which are based primarily on gold, silver and palladium and add 0.5% to 10% indium alloy.


After adding a small amount of indium metal dental inlay material, can significantly improve the corrosion resistance and hardness of filled material.

Indium product applications
Certain compounds of indium such as oxides, sulfides, and phosphates, are used in the manufacture of yellow and orange colored glasses, and in special optical glasses. Indium borate glass contained bismuth or cadmium that absorbs moderate intensity X rays and absorbs neutrons of higher specific heat neutrons.
Indium halides, such as indium iodide, are commonly used as additives in metal halide lamps, designed to increase the output power of lighting and to improve the quality of the spectrum.
