Kodi pali kusiyana kotani pakati pa kutentha kwakukulu kwa calcined α alumina ufa ndi white corundum

Kutentha kwambiri calcined α alumina micropowder ndi corundum woyera zonse kukonzedwa kuchokera mafakitale kalasi aluminiyamu ufa monga zopangira, koma processing luso ndi osiyana, ndipo chomalizidwa amakhalanso ndi zosiyana. Kutentha kwambiri calcined α alumina ufa amakonzedwa ndi ng’anjo kapena ng’anjo yozungulira pa 1300-1400 ° C. Imakhala ndi kukana kutentha kwambiri komanso kukana kuvala, chifukwa chake imagwiritsidwa ntchito kwambiri pazinthu zotsutsana ndi mafakitale a ceramic. White corundum imapangidwa ndi kusungunula pa kutentha kwakukulu kuposa madigiri a 2000 mu arc yamagetsi ndiyeno itakhazikika. Amaphwanyidwa ndi kuumbidwa, kupatukana ndi maginito kuti achotse chitsulo, ndi kusefedwa mu makulidwe osiyanasiyana. Chifukwa corundum yoyera ili ndi makhiristo wandiweyani, kuuma kwambiri, ndi ngodya zakuthwa, ndiyoyenera kupanga zoumba. , Die abrasives, kupukuta, sandblasting, mwatsatanetsatane kuponyera, etc. Angagwiritsidwenso ntchito kupanga apamwamba kalasi zipangizo refractory. Ndi abrasive yofunika kwambiri.

Kutentha kwambiri kwa α-alumina micropowder ndikosavuta kukonza, ndipo mtengo wopangira nawonso ndiwotsika, motero umagwiritsidwa ntchito kwambiri m’mafakitale okanira ndi ceramic. Chepetsani ndalama zopangira pokwaniritsa zosowa za makasitomala.

Kuphatikiza apo, ufa wopangidwa bwino kwambiri wama calcined alumina ufa ungagwiritsidwenso ntchito mu maenvulopu apakompyuta, ma spark plugs ndi zida zina zamagetsi zamagetsi, mphete zosindikizira, zoumba zosagwira ntchito monga makina a nsalu, ma crucibles alumina, machubu adothi ndi zina zotentha kwambiri. zipangizo, high-frequency insulating ceramics, LCD substrates Glass etc.
