Alumina ufa ndi chinthu choyera kwambiri, chopangidwa ndi aluminium oxide (Al2O3) chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.Ndi ufa woyera wa crystalline umene umapangidwa kupyolera mu kuyenga kwa bauxite ore.Alumina ufa ali ndi zinthu zambiri zofunika, kuphatikizapo kuuma kwakukulu, kukana mankhwala, ndi kutsekemera kwa magetsi, zomwe zimapangitsa kuti zikhale zofunikira m'mafakitale ambiri.

Kugwiritsa ntchito Aluminium Oxide Powder
1.Ceramic Viwanda: zida zadothi zamagetsi, zowuma zowumbidwa, ndi zida zapamwamba zaukadaulo.
2.Mafakitale Opukuta ndi Abrasive: magalasi a kuwala, zowotcha za semiconductor, ndi malo azitsulo.
3.Catalysis
4.Thermal Spray Coatings: Azamlengalenga ndi mafakitale amagalimoto.
5.Electrical Insulation
6.Refractory Industry: ng'anjo ya ng'anjo, chifukwa cha malo ake osungunuka kwambiri komanso kukhazikika kwabwino kwa kutentha.
7. Zowonjezera mu Ma polima
8.Zina: monga zokutira yogwira, adsorbents, chothandizira ndi chothandizira zothandizira, vacuum ❖ kuyanika, magalasi apadera zipangizo, composite zipangizo, utomoni filler, bio-ceramics etc.
