Indiyning kashf etilishining qisqacha tarixi

Indiy elementi 1863 yilda germaniyalik Reyx va Rixter tomonidan sfaleritni spektrometriya usulida o‘rganganlarida kashf etilgan.

The discovery of indium is due to the discovery of the element thallium. After thallium was discovered and obtained, Reich, a professor of physics at the Freiberg School of Mines in Germany, was interested in some properties of thallium and hoped to get enough metal for experiments. Research. He began searching for the metal in 1863 at the zinc mines at Himmelsfüst in Freiburg. The main components of this ore are arsenic-containing pyrite, sphalerite, leadite, silica, manganese, copper and a small amount of tin and cadmium. Reich thinks it may also contain thallium. Although the experiment took a lot of time, he did not get the desired element. However, he got a straw-yellow precipitate of unknown composition, which he believed to be a sulfide of a new element.

Bu farazni faqat spektrlardan foydalangan holda tahlil qilish isbotlashi mumkin. Biroq, Reyx rang ko'r edi va uning yordamchisi XT Rixterdan spektral tahlil tajribalarini o'tkazishni so'rashga majbur bo'ldi. Rixter birinchi tajribada muvaffaqiyat qozondi. U spektroskopda indigo ko'k yorqin chiziqni topdi. Lavozim seziyning ikkita ko'k yorqin chizig'iga to'g'ri kelmadi. Yunoncha"indikon" (indikon) Uni indiy (indiy) deb nomlang. Ikki olim birgalikda indiy kashfiyoti haqidagi hisobotni imzoladilar. Metall indiyni ajratish ikkalasi tomonidan amalga oshirildi. Ular dastlab xlorid va indiy gidroksidini ajratib olib, 1867 yilda Frantsiya Fanlar akademiyasida ko'rgazmaga qo'yilgan puflagich yordamida uni ko'mirda metall indiyga aylantirdilar.
