Raws li cov khoom siv tseem ceeb hauv cov khoom siv niaj hnub no thiab cov thev naus laus zis, kev ua haujlwm ntawm cov iav hluav taws xob ncaj qha txiav txim siab qhov pom kev thiab kev ntseeg siab ntawm cov khoom kawg. Tawm tsam keeb kwm yav dhau los ntawm txoj kev loj hlob sai ntawm kev lag luam zaub tshiab, kev nkag siab tob txog nws cov txheej txheem muaj pes tsawg leeg yog qhov tseem ceeb rau kev txhawb nqa cov khoom siv tshiab thiab kev hloov kho cov txheej txheem.
Los ntawm cov tshuaj muaj pes tsawg leeg pom, cov iav hluav taws xob yog ua raws li cov txheej txheem silicate, nrog rau kev ua kom zoo dua qub los ntawm kev tswj hwm cov oxide piv. Cov khoom tseem ceeb muaj xws li silicon dioxide (SiO₂), aluminium oxide (Al₂O₃), thiab boron oxide (B₂O₃). SiO₂ tsim cov txheej txheem network, muab cov iav yooj yim lub zog thiab tshuaj lom neeg ruaj khov; Al₂O₃ txhim kho lub iav huab cua tiv thaiv thiab cov khoom siv tawv tawv, txo qhov deformation thaum lub sijhawm ua haujlwm kub -; thiab B₂O₃ txo cov melting kub thiab txhim kho yaj flowability, ua rau nws tshwj xeeb tshaj yog haum rau kev npaj ntawm saj zawg zog hluav taws xob iav uas yuav tsum tau tsawg - kub forming. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev kov thiab tso saib daim ntawv thov, alkali hlau oxides (xws li Na₂O thiab K₂O) feem ntau tau qhia rau hauv cov qauv los kho cov coefficient ntawm thermal expansion. Ib txhij, cov ntsiab lus ntawm kev hloov pauv hlau impurities xws li hlau thiab chromium yog tswj nruj me ntsis- cov ntsiab lus no ua rau lub teeb nqus tau zoo, ua rau txo qis hauv iav transmittance. Yog li ntawd, kev xaiv thiab pretreatment ntawm siab - purity raw khoom yog qhov tseem ceeb heev.
Innovation nyob rau hauv cov txheej txheem muaj pes tsawg leeg yog ntxiv reflected nyob rau hauv cov kev taw qhia ntawm functional Cheebtsam. Piv txwv li, ntxiv zinc oxide (ZnO) los yog indium tin oxide (ITO) precursors tuaj yeem tsim cov txheej txheem pob tshab ntawm cov iav nto, ua tau raws li qhov yuav tsum tau muaj ntawm kev hnov mob. Doping nrog cov ntsiab lus tsis tshua muaj hauv ntiaj teb (xws li cerium thiab lanthanum) tuaj yeem txwv cov duab - kev laus los ntawm kev hloov pauv hauv ionic valence xeev, txuas ntxiv lub neej ntawm cov khoom siv. Tsis tas li ntawd, rau kev txhim kho cov iav hluav taws xob hloov tau yooj yim, qee cov qauv qhia me me ntawm lithium oxide (Li₂O) lossis phosphorus oxide (P₂O₅) txhawm rau txhim kho cov iav qhov yooj yim thaum tuav lub zog, kov yeej cov kev txwv ntawm cov tsoos tawv tawv substrates.
Thaum lub sij hawm kev npaj, kev sib koom ua ke ntawm cov qauv tsim thiab cov txheej txheem tsis yog qhov tseem ceeb. Thaum lub sij hawm melting theem, qhov kub thiab txias profile (feem ntau yog 1300-} 1600 degree) thiab lub sij hawm yuav tsum tau hloov kho raws li cov yam ntxwv ntawm cov khoom kom ntseeg tau tias cov oxides reacts tag nrho thiab tsim ib homogeneous yaj. Nyob rau hauv txoj kev tsim, cov txheej txheem xws li ntab iav thiab overflow rub -down iav yog siv los tswj cov iav thickness thiab nto flatness. Ultra-thin electronic iav (thickness<0.1mm) places even higher demands on the thermal stability of the components and forming precision. Subsequent annealing can eliminate internal stress and further optimize optical uniformity and mechanical properties.
Cov txheej txheem muaj pes tsawg leeg ntawm cov iav hluav taws xob sawv cev rau kev sib sib zog nqus ntawm cov ntaub ntawv tshawb fawb thiab cov txheej txheem thev naus laus zis, yuav tsum muaj qhov sib npaug ntawm qhov kev ua tau zoo, kev ua haujlwm nthuav dav, thiab daim ntawv thov scenarios. Raws li cov khoom siv thev naus laus zis hloov zuj zus mus rau qhov siab txhais, yoog raws, thiab kev siv hluav taws xob tsawg, nws cov qauv tsim yuav txuas ntxiv txhim kho mus rau siab purity, multifunctionality, thiab customization, muab kev txhawb nqa tseem ceeb rau kev kho dua tshiab.
