Indium is a very soft, silvery-white, relatively rare poor metal with a bright luster. When it is bent, indium emits a high-pitched "cry". Like gallium, indium is able to wet glass. Indium has a low melting point, 156.60 °C (313.88 °F); it is higher than that of its lighter homologue, gallium, but lower than that of the heavier homologue, thallium. Its boiling point is, however, moderate, being 2072 °C (3762 °F), which is higher than that of thallium, but lower than that of gallium, showing opposition to melting points trend. The density of indium, 7.31 g•cm−3, is also higher than that of gallium, but lower than that of thallium.

Indium's current primary application is to form transparent electrodes from indium tin oxide (ITO) in liquid crystal displays and touchscreens, and this use largely determines its global mining production. It is widely used in thin-films to form lubricated layers (during World War II it was widely used to coat bearings in high-performance aircraft). It is also used for making particularly low melting point alloys, and is a component in some lead-free solders.

Applications: Electronics, Metal and alloys:
Electronics: Indium oxide (In2O3) and indium tin oxide (ITO) are used as a transparent conductive coating applied to glass substrates in the making of electroluminescent panels.[38]
Some indium compounds such as indium antimonite, indium phosphide,[39] and indium nitride are semiconductors with useful properties.
Indium is used in the synthesis of the semiconductor copper indium gallium selenide (CIGS), which is used for the manufacture of thin film solar cells.
Used in light-emitting diodes (LEDs) and laser diodes based on compound semiconductors such as InGaN, InGaP that are fabricated by Metalorganic Vapor Phase Epitaxy (MOVPE) technology.
Ultrapure metalorganics of indium include high purity trimethylindium (TMI), which is used as a precursor in III-V compound semiconductors, while it is also used as the semiconductor dopant in II-VI compound semiconductors.

Metal and alloys: Very small amounts used in aluminum alloy sacrificial anodes (for salt water applications) to prevent passivation of the aluminum. To bond gold electrical test leads to superconductors, indium is used as a conducting adhesive and applied under a microscope with precision tweezers. In the form of a wire it is used as a vacuum seal and a thermal conductor in cryogenics and ultra-high vacuum applications. For example, in manufacturing gaskets which deform to fill gaps.
Used as a calibration material for Differential scanning calorimetry.
It is an ingredient in the gallium-indium-tin alloy Galinstan, which is liquid at room temperature while not being toxic like mercury.
