Application Field editor broadcast
Due to its strong photopermeability and electrical conductivity, indium is mainly used in the production of ITO target materials (for the production of liquid crystal displays and flat screens). This use is the main consumption area of indium ingot, accounting for 70% of the global consumption of indium.
The next few consumer sectors are: electronic semiconductors, accounting for 12% of global consumption; Solder and alloy sector accounted for 12%; Research accounted for 6%. In addition, because of its softer nature, it is also used in some industries that need to be filled with metal. Such as: vacuum gap filling material at higher temperature.
Medically, indium colloids are used for liver, spleen and bone marrow scans. Indium -DTPA for brain and kidney scans. Indium -Fe(OH)3 particles for lung scanning. Placental scan with indium-Fe-ascorbic acid. Inum ferritin delivery for hepatic cisterns. [2]
Gallium and indium are alloted to form a liquid metal, forming a solid solution that becomes liquid at room temperature and has a surface tension of 500 millinewtons per meter. This means that, when placed on a flat table without external forces, the alloy will remain an almost perfect ball. When stimulated by a small amount of electric current, the surface tension of the sphere will be reduced and the metal will stretch across the table. If the charge changes from negative to positive, the liquid metal becomes spherical again. Changing the voltage can also adjust the surface tension of the metal and the viscosity of the metal block, causing it to change into a different structure. The research could also be used to help repair severed nerves in humans to avoid long-term disability. The researchers claim the breakthrough could help build better electrical circuits and self-healing structures.
Chemical Properties editor
From room temperature to melting point, indium interacts slowly with oxygen in the air and forms an extremely thin oxide film (In2O3) on the surface. At higher temperatures, indium interacts with active non-metals. The bulk metal indium does not react with boiling water and alkali solutions, but in powder form indium can react slowly with water to form indium hydroxide. Indium reacts slowly with cold dilute acids and is easily soluble in concentrated hot inorganic acids, acetic acid and oxalic acid. Indium is alloyed with many metals (especially iron, which is significantly oxidized). The main oxidation states of indium are +1 and +3, and the main compounds of indium are In2O3, In(OH)3 and InCl3. When combined with halogens, indium can form a halide and trihalide respectively..
he distribution of indium in the Earth's crust is small and dispersed. Its rich deposits have not been found, but it exists as an impurity in zinc and some other metallic ores, so it is classified as a rare metal. [3]
Known indium minerals include CuInS2, FeInS4, and indium ore. Indium is mainly homogenous in marmatite, hematite, galena and other polymetallic sulfide ores. Indium is also found in cassiterite, wolframite and common amphibolite. In industry, the main source of indium is sphalerite (containing indium 0.0001 ~ 0.1%), which is recovered as a by-product in the smelting process of lead-zinc ore, and indium is also recovered in tin smelting.
Indium, a rare metal, is a scarce resource. The world's estimated reserves of indium are only 50,000 tonnes, of which 50 per cent is recoverable. Since no independent indium ore has been found, the industry produces indium by purifying waste zinc and tin with a recovery rate of about 50-60%. In this way, only 15,000-16,000 tons of indium can be truly obtained.
Physical properties editor broadcast
Indium is a silver-gray, extremely soft, fusible metal. Melting point 156.61ºC. Boiling point 2060ºC. Density 7.30g/cm3. Liquid indium can infiltrate glass and stick to contact surfaces, leaving black marks.
Indium is weakly radioactive and naturally has two main isotopes, of which In-113 is a stable nuclide and In-115 is a beta decay. Therefore, avoid direct contact as much as possible in use.
Indium metal can increase the critical current density of magnesium diboride superconducting
Adding indium metal powder to superconductor magnesium diboride has greatly increased the critical superconducting current density of magnesium diboride, which is a step forward to its practical application. The superconductor loses superconductivity when the current density passing through it exceeds a certain value, which is the critical current density of superconductivity. It is an important index to measure the performance of superconductors. The critical superconducting current density of magnesium diboride is four times higher than that without adding indium, reaching 100,000 amperes per square centimeter. This is the indium metal that penetrates between the grains of magnesium diboride, thus improving its binding.
