Abubuwan yumbu na aluminakayan yumbu masu aiki sosai waɗanda aka haɗa da aluminum oxide. Yawanci ana ƙera su ta hanyar tsarin tacewa mai zafi. Dangane da abubuwan da ke cikin alumina, ana rarraba su zuwa ƙananan tsarki (75%-85% Al₂O₃), matsakaicin tsarki (96% Al₂O₃), da kuma babban tsarki (≥99% Al₂O₃). Waɗannan abubuwan da aka yi amfani da su a cikin ƙananan tsari da halayen sinadarai masu ƙarfi, suna nuna ƙarfin injiniya mai ban mamaki, juriya mai zafi, da kuma rufin lantarki. Ana amfani da su sosai a matsayin kayan tushe a cikin kayan lantarki, tsarin wutar lantarki, sararin samaniya, da sauran masana'antu masu ci gaba.
Fa'idodin Alumina Ceramic Substrates:
Rufin Wutar Lantarki Na Musamman
Tare da juriya mai yawa (>10¹⁴ Ω·cm) da ƙarancin dielectric constant (8-10), yumburan alumina suna ware kwararar wutar lantarki yadda ya kamata, suna hana raguwar da'ira a cikin yanayi mai yawan mita ko ƙarfin lantarki mai yawa.
Babban Tsarin Zafin Jiki
Ƙananan abubuwa masu sinadarin alumina 96% suna ba da damar watsa zafi na 24-28 W/(m·K), wanda hakan ke ba da damar watsa zafi mai inganci daga kayan lantarki don hana zafi fiye da kima da kuma tsawaita tsawon rayuwar na'urar.
