Yumburan alumina masu ƙarfi: kayan aiki masu inganci tare da kyakkyawan aiki

Ana amfani da yumbun alumina sosai a fannoni da dama saboda fa'idodinsu kamar ƙarfin tauri da kuma ƙarfin juriyar sinadarai. Duk da haka, karyewarsu tana iyakance yawan amfani da su. An samar da yumbun alumina mai ƙarfi kuma ya magance wannan matsala yadda ya kamata.

 Yumburan alumina masu ƙarfiana iya taurare ta hanyoyi daban-daban. Nau'ikan da aka fi sani sun haɗa da taurarewar zirconia, wanda ke inganta tauri sosai ta hanyar ƙara ZrO₂ zuwa alumina da amfani da canjin yanayinsa da sauran hanyoyin; taurarewar wisker da zare, ƙara wiskers SiC, Si₃N₄ ko C, SiC zare don ƙara hanyoyin yaɗuwar fasa da kuma cinye kuzarin karyewa; taurarewar barbashi shine ƙara manyan barbashi masu roba kamar SiC da TiC don karkatar da fasa da kuma raba su.

 Ƙarfin lanƙwasa da ƙarfin tasirin tukwanen alumina masu tauri sun inganta sosai. Misali, ƙarfin lanƙwasa na tukwanen alumina masu tauri na zirconia na iya kaiwa 480MPa, kuma ƙarfin tasirin shine 7MPam1/2.

 Dangane da amfani, a fannin likitanci, ana amfani da shi don kera dashen hakori da gidajen haɗin gwiwa na wucin gadi saboda kyakkyawan jituwa da yanayinsa da kuma ƙarfinsa mai yawa, wanda zai iya rage matsaloli; a fannin semiconductor, a matsayin substrate na marufi na na'ura, ana amfani da shi a cikin IGBTs na abin hawa na lantarki, da sauransu saboda kyawun watsawar zafi, rufi da ƙarfin injina; a cikin kayan aikin yankewa, yana iya zama mai karko a yanayin zafi mai yawa kuma yana aiwatar da sarrafa ƙarfe da ƙarfe. Tukwanen alumina masu ƙarfi suna haskakawa a cikin ƙarin fannoni tare da kyakkyawan aikinsu. Tukwanen Chemshun suna samar da tukwanen alumina masu tauri tare da juriya ga lalata abincin dare da juriya ga tasirin tsarin sarrafa kayan da yawa.
