انڊيم

انڊيم (Indium) هڪ ڪيميائي عنصر آهي؛ ان جو نشان In ۽ ايٽمي نمبر 49 آهي. اهو هڪ چانديءَ جهيڙي اڇي رنگ جو منتقلي واري ڌاتن کان پوء جي نرم ترين عنصرن مان هڪ آهي. ڪيميائي طور تي، انڊيم گيليم ۽ ٿيليم سان ملندڙ جلندڙ آهي، ۽ ان جون خاصيتون وڏي حد تائين ٻنهي جي وچ ۾ آهن. ان کي 1863ع ۾ فرڊيننڊ ريخ ۽ هيرونيمس ٿيوڊور رچرٽر پاران اسپيڪٽروسڪوپڪ طريقن سان دريافت ڪيو ويو ۽ ان جي اسپيڪٽرم ۾ آسماني نيري (Indigo) لڪيرن جي نالي تي رکيو ويو.

تفصيل

Indium is a chemical element; it has symbol In and atomic number 49. It is a silvery-white post-transition metal and one of the softest elements. Chemically, indium is similar to gallium and thallium, and its properties are largely intermediate between the two. It was discovered in 1863 by Ferdinand Reich and Hieronymous Theodor Richter by spectroscopic methods and named for the indigo blue line in its spectrum.

Indium is used primarily in the production of flat-panel displays as indium tin oxide (ITO), a transparent and conductive coating applied to glass. It is also used in the semiconductor industry, in low-melting-point metal alloys such as solders and soft-metal high-vacuum seals. It is produced exclusively as a by-product during the processing of the ores of other metals, chiefly from sphalerite and other zinc sulfide ores.

Indium has no biological role and its compounds are toxic when inhaled or injected into the bloodstream, although they are poorly absorbed following ingestion.
