Alumina hmoov yog ntau yam khoom siv thoob plaws ntau yam kev lag luam. Ceramics tsim los ntawm nws nthuav tawm cov yam ntxwv tshwj xeeb ntawm kev ua haujlwm.
Cov hauv qab no yog qee qhov kev siv ntawm alumina hmoov:
Abrasives-Alumina hmoov, tshwj xeeb tshaj yog qib siab- purity qib, yog hnav- tiv taus, ua rau nws zoo tagnrho rau siv hauv kev sib tsoo xov xwm, ntawv xuab zeb, thiab lwm yam khoom siv abrasive.
Cov ntaub ntawv biomedical-Ceramics ua los ntawm alumina hmoov muaj cov biocompatibility zoo heev thiab yog siv los tsim cov pob qij txha thiab pob txha, cov hniav hniav, thiab lwm yam kev cog hniav.
Ceramic Cheebtsam-feem ntau yog ua los ntawm 99.0% ntshiab alumina hmoov, cov khoom no muaj siab -kub tsis kam, tso cai rau lawv ua hauj lwm zoo nyob rau hauv siab - av noo ib puag ncig.
Electronics -Alumina hmoovmuaj cov khoom zoo thermal thiab hluav taws xob rwb thaiv tsev. Nws yog siv los tsim cov high-voltage insulators, hluav taws xob vaj tse, thiab substrates.
Engineering ceramics-Cov ntaub ntawv no yog siv rau hauv kev siv qib siab lossis nyuaj, xws li kev tsim khoom semiconductor, chemical vapor deposition (CVD) txheej txheem, thiab photolithography.
Kev tsim cov ntaub ntawv no yuav tsum muaj siab -purity alumina hmoov los xyuas kom meej hnav tsis kam, tshuaj lom neeg ruaj khov, thiab ua haujlwm kub.
Fillers-Alumina hmoov yog cov khoom siv muab tub lim, pab cov khoom xws li roj hmab thiab yas tiv taus qhov kub thiab txias thiab kev ntxhov siab.
iav-Vim nws lub zog hardness thiab compressive zog, alumina hmoov tuaj yeem siv los ua iav mos txwv thiab tawg tau-resistant.
Laboratory ware-Nrog nws qhov siab melting point thiab tshuaj stability, alumina hmoov yog ib qho khoom siv zoo tshaj plaws rau cov cuab yeej siv hauv kev sib tsoo thiab cua sov cov tshuaj sib xyaw.
Refractories- Cov ntaub ntawv refractory yuav tsum tau thermal shock resistance thiab lub siab melting point; alumina hmoov muaj ob qho tib si ntawm cov yam ntxwv no.
Kev siv cov hmoov Alumina
Thaum tsim alumina ceramics, kev xaiv ntawm alumina hmoov nyob ntawm ob yam: hom thiab purity. Nws yog qhov zoo tshaj plaws los xaiv cov qib uas muaj qhov zoo tshaj plaws rau cov khoom tshwj xeeb.
Piv txwv li, yog tias yuav tsum muaj qhov hnyav hnyav, calcined alumina hmoov yog qhov kev xaiv zoo heev.
Hom Alumina Hmoov
Nws raug nquahu kom siv tsuas yog alumina hmoov uas ua tau raws li qhov tshwj xeeb ntawm koj daim ntawv thov tshwj xeeb. Hmoov zoo, muaj peb yam tseem ceeb ntawm alumina hmoov muaj rau xaiv los ntawm, txawv los ntawm cov hauv qab no:
Lawv cov hlau (Fe2O3), silica (SiO2), thiab sodium (Na2O) cov ntsiab lus
Qib purity thiab cov khoom tshwj xeeb ntawm alumina hmoov siv hauv cov txheej txheem ntau lawm
