Cov iav txheej yog qhov saum npoo ntawm cov iav uas muaj ib lossis ntau txheej ntawm cov hlau, hlau oxide lossis lwm yam khoom, lossis cov hlau ions uas tau tsiv teb tsaws chaw. Cov iav txheej hloov qhov kev cuam tshuam, qhov ntsuas refractive, kev nqus thiab lwm yam khoom ntawm cov iav rau lub teeb thiab cov nthwv dej electromagnetic, thiab muab cov khoom tshwj xeeb rau ntawm qhov chaw iav. Cov thev naus laus zis tsim cov iav txheej tau dhau los ua qhov paub tab dua, cov khoom lag luam thiab cov haujlwm txuas ntxiv mus ntxiv, thiab qhov ntau thiab tsawg ntawm daim ntawv thov tau nthuav dav.
Kev faib tawm ntawm cov iav coated tuaj yeem faib ua pawg raws li cov txheej txheem tsim khoom lossis kev siv. Raws li cov txheej txheem tsim khoom, muaj cov iav coated online thiab cov iav coated off-line. Cov iav coated online yog coated rau ntawm qhov chaw iav thaum lub sijhawm tsim cov iav ntab. Hais lus zoo, cov iav coated off-line yog ua tiav sab nraum cov kab tsim iav. Cov iav coated online suav nrog cov dej ntws hluav taws xob, cov pa tshuaj lom neeg thiab cov tshuaj tsuag thermal, thiab cov txheej txheem off-line suav nrog cov dej nqus tsev, cov dej nqus tsev, cov kua qaub-gel thiab lwm yam.
Raws li kev siv ua haujlwm ntawm cov iav coated, nws tuaj yeem faib ua lub hnub ci tswj cov iav coated,iav qis-e, iav zaj duab xis conductive, iav ntxuav nws tus kheej,iav tiv thaiv kev cuam tshuam, iav iav, iav ci ntsa iab, thiab lwm yam.
Hauv ib lo lus, rau ntau yam laj thawj, suav nrog qhov yuav tsum tau ua rau cov khoom siv hluav taws xob thiab kho qhov muag tshwj xeeb, kev khaws cia cov khoom siv, kev ywj pheej hauv kev tsim qauv engineering, thiab lwm yam, kev txheej yog qhov xav tau lossis tsim nyog. Kev txo qis zoo yog qhov tseem ceeb heev hauv kev lag luam tsheb, yog li cov khoom siv hlau hnyav (xws li cov grids) raug hloov nrog cov khoom yas sib dua plated nrog chromium, txhuas thiab lwm yam hlau lossis alloys. Lwm daim ntawv thov tshiab yog txheej indium tin oxide zaj duab xis lossis cov hlau tshwj xeeb ceramic zaj duab xis ntawm lub qhov rais iav lossis yas ntawv ci kom txhim kho kev ua haujlwm txuag hluav taws xob ntawmcov tsev.
Saida Glasssiv zog ua koj tus khub txhim khu kev qha thiab cia koj hnov cov kev pabcuam muaj nqis ntxiv.
