And indium-115 is the most abundant isotope. There are only two naturally occurring isotopes, indium-113 and indium-115. Indium has thirty-nine isotopes, which range in mass number from 97 to 135. Indium toxicity is mostly an occupational hazard and personals can develop symptoms of toxicity through ingestion, eye contact, inhalation and contact with skin. It damages the kidneys and is more toxic in aqueous solution as compared to direct injection of metal into the body. Indium (III) is toxic to the body if ingested. Radioactive isotope of indium (indium-111) is used in nuclear medicine studies for the movement of blood cells in the body.It is used as control rod in nuclear reactors.Indium is used in amalgam alloys used for dental purposes.It is used in cryogenic applications for the study and production of various materials at low temperature.Indium is used in the manufacturing of ultra-high-vacuum applications, such as various electron and X-rays electro-photon spectroscopy.indium oxides are used as conductive coating on glass in electroluminescent panels.

This accounts for around half of the worldwide usage of indium. It is used in the manufacturing of LCD screens for television and computer monitors. Indium is widely used in the semiconductor industry.The most common oxidation state of indium is +2. When burned in air, indium (III) forms indium oxide, which can react with both acids and base (an amphoteric compound). Indium does not react with base and is insoluble in alkaline solutions. Reaction of halogens with indium lead to the production of indium (III) compounds. Indium has the ability to become a superconductor below the critical temperature. Indium has a low melting point (156.60 C) and boiling point is 2072 C. The largest producer of indium is China, followed by Canada, Japan and South Korea. Commercially, indium is obtained as a byproduct during the refining of zinc sulfide ores. Naturally, it is present in little amounts with ores of copper, lead, iron and zinc. Indium does not have any ore that contain high concentration of this metal. It is not present in elemental or free form. Indium is present in Earth’s crust in around 0.21 ppm. In 1950, indium beads were used in junction transistors. In its early days, indium was used as a coating agent of bearing of aircraft engines in World War II. The name indium was given to the novel element for its indigo blue line in its spectrum. In 1863, Hieronymous Richter and Ferdinand Reich discovered indium by spectroscopic methods. Indium has no biological role but is toxic when inhaled or ingested. It was discovered it 1863 and have found wide use in making semiconductors and transistors. Indium is characterized as post transition metal.
