The stable indium isotope, indium-113, is one of the p-nuclei, the origin of which is not fully understood; although indium-113 is known to be made directly in the s- and r-processes (rapid neutron capture), and also as the daughter of very long-lived cadmium-113, which has a half-life of about eight quadrillion years, this cannot account for ...

To obtain the trialkyl derivatives, alkylation of indium trihalides with organolithium reagents is typical. [4] OrganoIn(III) compounds are also prepared by treating In metal with alkyl halides. This reaction gives mixed organoindium halides. Illustrative is the reaction of allyl bromide with a THF suspension of indium.
Advantages of indium cryogenic seals: Established/proven design techniques for indium seal assembly [6] [7] Option for disassembly and re-assembly [2] Indium can be reformed into useful seals after use [7] Soft and pliable at room temperature, due to the low melting temperature of indium, so it fills imperfections.
Indium phosphide (InP) is a binary semiconductor composed of indium and phosphorus. It has a face-centered cubic ("zincblende") crystal structure, identical to that ...
Indium is a soft, malleable, silver, shiny metal with atomic weight of 114.818 and resides as number 49 on the Chemical Periodic Table. Indium is a superconductor below 3.4 K, has a resistance of 8.8 micro-ohms at 20 C, a melting point of 156.598 C, a boiling point of 2027 Cº, and a density of 7.31 g/cc. [1] Indium can be alloyed with a wide range of other metals to lower their melting point.
Galinstan is a brand name for an alloy composed of gallium, indium, and tin which melts at −19 °C (−2 °F) and is thus liquid at room temperature. [4] [5] In scientific literature, galinstan is also used to denote the eutectic alloy of gallium, indium, and tin, which melts at around +11 °C (52 °F). [5]
InCl can be prepared by heating indium metal with indium trichloride in a sealed tube. [3] [4] According to X-ray crystallography, the structure of the yellow polymorph resembles that of sodium chloride except that the Cl-In-Cl angles are not 90°, but range between 71 and 130°. The red (high T) polymorph crystallizes in the thallium(I) iodide ...
