Alumina ceramic qhov chawyog dav siv hauv cov khoom siv teeb pom kev zoo, cov khoom siv hluav taws xob cua sov, petrochemicals, machinery, textiles, tsheb thiab lwm yam lag luam. Dab tsi yog kev faib tawm thiab cov yam ntxwv ntawm alumina ceramic qhov chaw?
Alumina ceramic qhov chaw tau muab faib ua hom high-purity thiab zoo tib yam, tseem hu ua alumina ceramic qhov chaw.
Cov yam ntxwv ntawm ob hom alumina ceramic qhov chaw:
1. High-purity alumina ceramic qhov chaw yog cov khoom siv ceramic nrog Al2O3cov ntsiab lus ntau dua 99.9 feem pua. Txij li thaum lawv cov sintering kub yog siab li 1650-1990 degree, kis tau tus mob wavelength yog 1-6 μm.
Nws yog feem ntau ua los ntawm molten iav los hloov platinum crucibles: nws yog siv los ua ib lub teeb sodium raj los ntawm nws lub teeb transmittance thiab alkali hlau corrosion kuj; nws tuaj yeem siv los ua ib qho kev sib txuas hauv Circuit Court substrate thiab cov khoom siv hluav taws xob ntau zaus hauv kev lag luam hluav taws xob.
2. Ordinary alumina ceramic qhov chaw muab faib ua 99 plooj (porcelain), 95 plooj (porcelain), 90 plooj (porcelain), 85 plooj (porcelain) thiab lwm yam ntau yam raws li cov ntsiab lus ntawm Al2O3. Qee zaum cov nrog Al2O3Cov ntsiab lus ntawm 80 feem pua lossis 75 feem pua yog tseem raug cais raws li cov khoom siv alumina ceramic.
Ntawm lawv, 99 alumina ceramic cov ntaub ntawv yog siv los ua kub kub crucibles, refractory furnace tubes thiab tshwj xeeb hnav-resistant cov ntaub ntawv, xws li ceramic bearings, ceramic seals thiab dej valve pieces. 95 alumina porcelain feem ntau yog siv los ua corrosion-resistant thiab hnav-resistant qhov chaw; 85 plooj (porcelain) feem ntau yog tov nrog ib feem ntawm talc, uas txhim kho cov khoom siv hluav taws xob thiab cov khoom siv dag zog, thiab tuaj yeem muab khi nrog molybdenum, niobium, tantalum thiab lwm yam hlau, thiab qee qhov yog siv rau lub tshuab nqus tsev twj.
Lwm lub ntsiab lus uas yuav tsum tau them sai sai rau yog: qhov kub ntawm cov khoom no muaj kev nyab xeeb rau kev siv. Nco ntsoov tias qhov ntsuas kub ntawm corundum zoo yog<1600ºc, and="" the="" temperature="" of="" high="" aluminum="" quality="" is="" less="" than="">
