Alumina, los yog txhuas cov pa oxyde, tuaj yeem tsim nyob rau hauv ntau yam ntawm kev coj dawb huv. Cov qhab nia raug uas tau siv rau cov ntawv thov niaj hnub yog 99.5% rau 99.9% nrog cov tshuaj ntxiv uas tsim los txhim kho cov khoom. Ntau hom kev ua lag luam ceramic tuaj yeem siv tau xws li machining lossis net graph tsim kom muaj ntau qhov ntau thiab tsawg thiab cov duab ntawm cov khoom siv.

Alumina yog cov khoom siv sib xyaw ua ke dav hauv cov ntawv thov hauv qab no:

Inster Hluav taws xob insulators, corrosion-tiv taus roj av, rau cov khoom siv ua roj (xws li chuck, Laib Laus, Foob Assib)

Inser Hluav taws xob insulators rau cov leeg electron.

■ Cov qauv txheem qhov chaw rau cov khoom siv tshuab siab thiab cryogenic cov khoom siv, cov khoom siv hluav taws xob nuclear hluav taws xob, cov khoom siv siv thaum muaj qhov kub.

■ Cheebtsam, piston rau twj, li qub thiab dosing tshuab, ntsuas cov ntshav li qub.

■ Cov leeg hluav taws xob thermocouple, insulator insulators, sib tsoo xov hlau, xov.
