Cov khoom siv ceramics ua los ntawm peb lub tuam txhab muaj kev tiv taus kub, corrosion, hnav thiab rwb thaiv tsev, thiab tuaj yeem ua tau. siv rau lub sijhawm ntev hauv qhov kub thiab txias, lub tshuab nqus tsev thiab corrosive gas ib puag ncig.

Dav siv nyob rau hauv ntau yam khoom siv semiconductor: Ncej (ceramic bracket), Substrate (base), Arm / Choj (manipulator), , Mechanical Cheebtsam thiab Ceramic Cua Bearing.

AL2O3

Daim ntawv thov ntawm siab purity alumina ceramics:
1. Siv rau cov khoom siv semiconductor: ceramic nqus chuck, txiav disc, ntxuav disc, ceramic CHUCK.
2. Wafer hloov qhov chaw: wafer tuav chucks, wafer txiav discs, wafer tu discs, wafer optical tshuaj xyuas lub khob.
3. LED / LCD vaj huam sib luag tiaj tus zaub kev lag luam: ceramic nozzle, ceramic sib tsoo disc, LIFT PIN, PIN rail.
4. Kev sib txuas lus kho qhov muag, hnub ci kev lag luam: ceramic raj, ceramic rods, circuit board screen printing ceramic scrapers.
5. Thaum tshav kub kub-resistant thiab hluav taws xob insulating qhov chaw: ceramic bearings.
Tam sim no, aluminium oxide ceramics tuaj yeem muab faib ua cov purity siab thiab ntau hom ceramics.Lub siab purity aluminium oxide ceramics series hais txog cov khoom siv ceramic uas muaj ntau tshaj 99.9% Al₂O₃.Vim tias nws qhov kub thiab txias txog li 1650 - 1990 ° C thiab nws qhov kev sib kis wavelength ntawm 1 ~ 6μm, nws feem ntau ua tiav rau hauv fused iav es tsis txhob platinum crucible: uas tuaj yeem siv los ua sodium raj vim nws lub teeb xa tawm thiab corrosion tsis kam. alkali hlau.Hauv kev lag luam hluav taws xob, nws tuaj yeem siv los ua cov khoom siv hluav taws xob ntau zaus rau IC substrates.Raws li cov ntsiab lus sib txawv ntawm txhuas oxide, cov txhuas oxide ceramics tuaj yeem muab faib ua 99 ceramics, 95 ceramics, 90 ceramics thiab 85 ceramics.Qee zaum, cov ceramics nrog 80% lossis 75% ntawm txhuas oxide kuj tau muab cais ua cov txhuas oxide ceramic series.Ntawm lawv, 99 aluminium oxide ceramic khoom siv los tsim cov khoom kub kub, hluav taws kub hauv qhov cub thiab cov khoom siv tshwj xeeb hnav, xws li ceramic bearings, ceramic seals thiab valve phaj.95 txhuas ceramics yog siv los ua corrosion-resistant hnav-tiv taus ib feem.85 ceramics feem ntau sib xyaw hauv qee yam khoom, yog li txhim kho hluav taws xob kev ua tau zoo thiab lub zog txhua yam.Nws tuaj yeem siv molybdenum, niobium, tantalum thiab lwm yam hlau ntsaws ruaj ruaj, thiab qee qhov siv los ua cov khoom siv hluav taws xob.
