Silica thiab txhuas muaj abundantly pom nyob rau hauv cov txheej no yog li nws yog nrov npe hu ua SIAL. Qhov nruab nrab ntom ntawm txheej yog 2.75 txog 2.90 thiab qhov nruab nrab thickness yog 8 mus rau 100 km.

Q: Muaj pes tsawg hom alumina muaj?

A: Alumina (hu ua txhuas oxide) hmoov raws li siv nyob rau hauv ceramics yuav ua tau ib tug dawb granular khoom (xws li lub rooj ntsev) los yog ib tug tshwj xeeb zoo silky dawb thiab tuab hmoov (nyob ntawm seb hom thiab ua txoj kev). Muaj peb hom alumina dav dav: Hydrated, calcined thiab tabular.

Q: Puas yog calcined alumina txaus ntshai?

A: Cov khoom no tsis raug cais raws li kev phom sij raws li Lub Ntiaj Teb Kev Sib Raug Zoo (GHS). tsim thaum siv yog teeb meem. Tsis muaj lwm yam kev phom sij tsis yog lwm yam uas tau raug txheeb xyuas.White fused alumina yog dav siv los ua cov khoom siv raw hauv cov khoom siv hluav taws xob, cov duab ceramics, sib tsoo log, ntawv xuab zeb, blasting media, hlau npaj, laminates, coatings, lapping, polishing, sib tsoo thiab pua pua. ntawm lwm yam kev siv.
