Xyoo 1877, tus kws tshaj lij Fab Kis Fab Kis, Fremy coj cov hmoov ntshiab alumina, potassium carbonate, barium fluoride thiab ib qho me me ntawm potassium dichromate ua cov ntaub ntawv nyoos, tom qab ntawd muab tso rau hauv ib qho ua kom tawg ntawm qhov kub txog li 8 hnub kom tau txais cov khoom me me ntawm xws li ruby siv lead ua. , uas yog qhov pib ntawm cov paj yeeb fused alumina.
Xyoo 1900, cov kws tshawb fawb tau tsim 2g ~ 4g ruby los ntawm kev ntxiv me me ntawm chromium oxide thiab Cr2O3 rau cov fused alumina raws li kev faib ua feem ntawm 0.7%. Txawm li cas los xij, tam sim no peb tuaj yeem ua cov paj yeeb fused alumina loj npaum li 10g.
Hauv nroog Geneva,
Xyoo 1891, Verneuil tau tsim cov txheej txheem nplaim hluav taws thiab siv nws los sim-tsim lub pov haum hluavtaws. Tom qab ua tiav, nws sim nws nrog ntshiab txhuas oxide. Ntawd yog, nyob rau hauv lub qhov cub kub ntawm qhov cua sov, nws tau sim nws nrog lub tshuab nqus pa oxygenhydrogen, kom cov nplua zoo ntawm cov ntshiab aluminium oxide uas muaj me me ntawm chromium oxide tau maj mam yaj mus rau hauv nplaim taws thiab poob rau hauv paus kom ua rau siab thiab crystallize.
Tom qab kaum lub xyoo ntawm kev siv zog, Verneuil tau tsim cov nyom ua kom zoo nkauj thaum xyoo 1904. Tom qab ntawd, cov nplaim hluav taws kev qhia tau maj mam hloov zuj zus, thiab lub ruby tsim los ntawm nws yuav luag tsis txawv ntawm cov khoom ntuj tsim. Cov qauv no tau siv txog thaum niaj hnub, thiab tseem yog tus qauv tseem ceeb ntawm kev tsim cov khoom coj ua hluav taws xob hauv ntiaj teb, uas hu ua" verneuil txujci" ;. Tab sis tam sim no, ntev npaum li ob peb teev, pob zeb ntxhib ntawm ruby tuaj yeem tsim, thiab cov tsos nws yog hom hluavtaws corundum siv lead ua nrog inverted pear-puab lossis duab puab. Ntxiv mus, nws muaj cov ntawv nyeem ntshiab thiab qhov pom tseeb tshaj qhov ntuj, ntxiv rau cov txiaj ntsig nyiaj txiag yog loj heev. Niaj hnub nimno “Verneuil txujci” tsis tsuas yog tsim lub ruby los ntawm daj ntseg liab rau tob liab, kuj tuaj yeem tsim ntau xim ntawm sapphire, thiab tseem tuaj yeem tsim ruby thiab sapphire nrog lub hnub qub, uas yog qhov zoo tshaj plaws artical excelling xwm.
Paj yeeb fused alumina feem ntau yog tsim los ntawm aluminium oxide hmoov thiab tom qab ntawd ntxiv nrog cov nqi tsim nyog ntawm chromium oxide. Lub hardness ntawm pink fused alumina zoo ib yam li qhov zoo ntawm dawb fused alumina, thiab lub tawv ntawm liab fused alumina yog siab dua qhov ntawm fused alum alumina. Ntxiv mus, cov cuab yeej sib tsoo ua los ntawm Pink fused alumina muaj kev ua kom zoo thiab siab kawg hauv kev sib tsoo. Nws yog tsim rau kev sib tsoo meej ntawm kev ntsuas cov cuab yeej, cov cuab yeej siv tshuab ntxaiv, qhov ntsuas qhov ntsuas, xov cov khoom ua haujlwm thiab cov qauv mills.
