7N Qib Txheeb Xyuas Shartz xuab zeb tau nkag mus ntau lawm!

Rau ib lub sijhawm ntev, kuv lub teb chaws Semiconductor kev lag luam cov saw hlau tau ruaj khov rau 7N-qib siab-huv sility quariconductor cov txheej txheem. Qhov no tau yog qhov tseem ceeb bottleneck hauv kev lag luam saw hlau. Raws li nti thev naus laus zis txuas ntxiv mus Evolve, cov txheej txheem ua ntej tau tso cov hlua khi siv tsis tau zoo kawg nkaus, thiab kev ruaj ntseg ntawm cov quartz substrate.

Tsis ntev los no, ib lub Hoobkas quartz lub Hoobkas tau ua tiav cov thev naus laus zis tseem ceeb los ntawm ntuj Quarationz ore Purification rau cov tshuaj lom neeg siab. Lawv tau tsim cov cuab yeej thev naus laus zis encompassing precompassing precursor technology, tshuaj kho cov txheej txheem tshuaj lom neeg, thiab cov ntaub ntawv pov thawj cov khoom siv. Lawv tau ua tiav tau zoo thiab loj tsim 7n-tsim 7n-tsim tawm (99.9999%) Synthety Cov ntsiab lus ntawm cov ntsiab lus tsis zoo tshaj 20 ppb, nrog cov cai tswjfwm kev paub ywj pheej. Qhov hluavtaws hluavtaws hluavtaws hluav taws xob no tau siv rau hauv kev tsim cov semiconductor-qib quartz crucibles, photolithographes, thiab etching cov txheej txheem, ntawm lwm cov txheej txheem tseem ceeb.

Txoj kev vam meej no tsis muaj kev huam yuaj. Lub tuam txhab tau ua tiav cov kev kawm tau zoo nyob rau hauv cov txheej txheem quartz, tsim muaj ntau yam khoom siv kev tshem tawm, xws li kev tswj hwm qhov tseem ceeb, kev siv tshuab ua ntej, thiab doping cov txheej txheem. Cov thev naus laus zis tau hloov pauv mus ua kev sib tw.

Txheej txheem rau synthesizing siab-purity quartz xuab zeb los ntawm silicon tetrachloride los ntawm kua-base hydrolysis

Qhov kev cuam tshuam cov txheej txheem rau synthesizing siab-huv Quartz xuab zeb los ntawm Silicon Tetrachloride los ntawm cov kua-theem hydrolysis. Cov txheej txheem cuam tshuam nrog kua-base hydrolysis ntawm silicon tetrachloride nrog dej. Cov khoom lag luam tsis huv, ua kua-ua kua sib cais, ziab khaub ncaws, kev suav, sib tsoo, thiab tshuaj ntsuam kom tau txais high-purity quartz hmoov. Cov cua sov muaj nyob rau hauv cov khoom siv hluav taws xob ua kom huv si, nruab nrab ntawm cov kua qaub thiab ua kom huv si los txhawb kev hloov pauv thiab tu thiab ntxuav, thiab txo cov khoom siv raw. Lub ziab kub yog 100-200 degree, thiab kev xam kub yog 1300-1500 degree. Lub rauv cua sov tsim yog qhov zoo rau kom ntseeg tau cov cua sov thiab tiv thaiv cov hmoov Akglomeration.

Cov txheej txheem rau npaj cov roj av ultra-siab-huv amorphous silica synthesized quartz xuab zeb

Cov txheej txheem no tso tawm cov txheej txheem npaj rau ultra-high-purity amorphous silica synthesized quartz xuab zeb. Cov txheej txheem cuam tshuam nrog lub siab-siab ntawm amorphous cov tshuaj tiv thaiv ntawm silica, thiab cov mineralizous, thiab ultrape dej sib cais thaum tso tawm. Cov khoom yog tom qab av, acid-ntxuav-ntxuav, ntxuav, thiab qhuav kom tau cov khoom. Cov txheej txheem no siv reantor siab kom ua tiav cov kua-kua sib cais thaum lub sijhawm tsis siv, txuag nqi. Nws tseem tab tom siv Amorphous silica, khav theeb siab thiab txhawb nqa qhov tsis txaus ntawm cov ore zoo quartz ore hauv kuv lub teb chaws. Lub resulting quartz xuab zeb muaj cov ntsiab lus tsawg, cov ntsiab lus tsawg thiab tsawg kawg ntawm cuaj impurities.

Ib tug semiconductor-qib hluav taws xob quartz npaj cov txheej txheem

No cov txheej txheem txhim kho hluavtaws-qib hluav taws xob muaj cov kauj ruam ntawm plaub: cov khoom tawg, kev sib pauv khoom, thiab kev ua kom muaj kev ua kom huv. Khoom siv npaj yuav cuam tshuam rau kev ntxiv cov khoom siv alkali silicate rau cov khoom siv thiab dissolving thiab diluting nws nrog dej nruab nrab. Kev tawm tsam los cuam tshuam nrog kev ntxiv cov impurity remover, nplawm, tso cai rau kev sib xyaw kom sib xyaw thiab lim kom sib hloov. Ion pauv pauv koom nrog kev daws teeb meem los sib pauv los ntawm cov ntaub acid muaj zog sib pauv sab rau tshem cov calcium thiab sodium ions, uas ua rau sol. Kev ua kom muaj kev lim tshuaj yuav tso cai rau sawv daws kom sawv ua kev laus, kev ntxuav, sintering, thiab ultra-high-curity purification kom tau cov khoom. Cov txheej txheem no siv cov khoom siv sib xyaw ua ke los txhim kho kev siv tshuab thiab kev ua tau zoo.
