Keeb kwm luv luv ntawm Discovery ntawm Indium

Lub caij indium tau pom nyob rau hauv 1863 los ntawm Reich thiab Richter ntawm lub teb chaws Yelemees thaum lawv kawm sphalerite los ntawm spectrometry.

Kev tshawb pom ntawm indium yog vim qhov kev tshawb pom ntawm lub caij thallium. Tom qab thallium tau tshawb pom thiab tau txais, Reich, tus xibfwb ntawm physics ntawm Freiberg Tsev Kawm Ntawv ntawm Mines hauv Tebchaws Yelemees, tau xav txog qee yam khoom ntawm thallium thiab vam tias yuav tau txais hlau txaus rau kev sim. Kev tshawb fawb. Nws pib tshawb nrhiav cov hlau hauv xyoo 1863 ntawm zinc mines ntawm Himmelsfüst hauv Freiburg. Cov khoom tseem ceeb ntawm cov ore no yog arsenic-muaj pyrite, sphalerite, leadite, silica, manganese, tooj liab thiab ib qho me me ntawm tin thiab cadmium. Reich xav tias nws kuj tseem muaj thallium. Txawm hais tias qhov kev sim siv sijhawm ntau, nws tsis tau txais cov khoom xav tau. Txawm li cas los xij, nws tau txais straw-daj precipitate ntawm tsis paub muaj pes tsawg leeg, uas nws ntseeg tau tias yog sulfide ntawm lub caij tshiab.

Tsuas yog kev tsom xam siv spectra tuaj yeem ua pov thawj qhov kev xav no. Txawm li cas los xij, Reich yog qhov muag tsis pom kev thiab yuav tsum tau nug nws tus pab cuam HT Richter los ua qhov kev sim ntsuas spectral. Richter tau ua tiav hauv thawj qhov kev sim. Nws pom ib tug indigo xiav ci kab nyob rau hauv lub spectroscope. Txoj hauj lwm tsis coincide nrog ob lub xiav ci kab ntawm cesium. Los ntawm Greek lo lus "indikon" (indikon) Lub npe nws indium (indium). Ob tus kws tshawb fawb tau koom ua ke kos npe rau daim ntawv tshaj tawm txog kev tshawb pom ntawm indium. Kev sib cais ntawm cov hlau indium tau ua tiav los ntawm ob qho tib si. Lawv thawj zaug cais cov tshuaj chloride thiab hydroxide ntawm indium thiab txo nws mus rau metallic indium ntawm charcoal siv lub tshuab blowpipe, uas tau nthuav tawm ntawm Fabkis Academy ntawm Kev Tshawb Fawb hauv xyoo 1867.
