Alumina, ko Aluminum Oxide, ana iya samar da shi cikin kewayon tsafta.Makiyoyi na yau da kullun waɗanda ake amfani da su don aikace-aikacen masana'antu na zamani sune 99.5% zuwa 99.9% tare da ƙari waɗanda aka tsara don haɓaka kaddarorin.Ana iya amfani da hanyoyin sarrafa yumbu iri-iri iri-iri ciki har da machining ko net form forming don samar da nau'i-nau'i iri-iri da nau'ikan sassa.
Al2O3 yumbura yana da fa'idodi masu zuwa:
1. High hardness (MOHS hardness ne 9) da kuma kyau lalacewa juriya.
2. Kyakkyawan ƙarfin injiniya.Ƙarfin lanƙwasa yana iya zuwa 300 ~ 500MPa.
3. Kyakkyawan juriya na zafi.Yana ci gaba da aiki zafin jiki zai iya zuwa 1000 ℃.
4. High resistivity da kyau lantarki rufi Properties.Musamman tare da insulating high zafin jiki mai kyau (Room-zazzabi resistivity ne 1015Ω•cm) da ƙarfin lantarki karya juriya (rufin rufi ne 15kV / mm).
5. Kyakkyawan kwanciyar hankali.Ba ya amsa da sulfuric acid, hydrochloric acid, nitric acid da hydrofluoric acid.
6. High zazzabi juriya lalata.Zai iya yin tsayayya da zaizayar ƙarafa kamar Be, Sr, Ni, Al, V, Ta, Mn, Fe da Co.
Sabili da haka, ana amfani da yumbu alumina a cikin filayen masana'antu na zamani.Yafi amfani da semiconductor masana'antu masana'antu, Electronics masana'antu, inji masana'antu, high zafin jiki yanayi, sinadaran masana'antu, haske masana'antu, yadi da sauran filayen.
Alumina kayan yumbu ne da ake amfani da su sosai a cikin aikace-aikacen masu zuwa:
✔ Insulators na lantarki, abubuwan juriya na juriya don laser gas, don kayan sarrafa semiconductor (kamar chuck, mai tasiri na ƙarshe, zoben hatimi)
✔ Insulators na lantarki don bututun lantarki.
✔ sassa na tsarin don kayan aiki masu ƙarfi da kayan aiki, na'urorin radiation na nukiliya, kayan aikin da ake amfani da su a yanayin zafi.
✔ Abubuwan juriya na lalata, piston don famfo, bawuloli da tsarin dosing, samfurin bawul ɗin jini.
✔ tubes na thermocouple, insulators na lantarki, kafofin watsa labaru, jagororin zaren.
