Alumina yumbu wani nau'i ne na kayan yumbu tare da Al2O3 a matsayin babban kayan albarkatun kasa da corundum (a-Al2O3) a matsayin babban lokaci na crystalline. Matsakaicin zafin jiki na yumbura alumina gabaɗaya ya fi girma saboda yanayin narkewar alumina har zuwa 2050 C, wanda ke sa samar da yumbu alumina yana buƙatar amfani da dumama zafin jiki ko kayan inganci masu inganci da manyan kayan refractories azaman kiln da kiln furniture. , wanda har zuwa wani lokaci yana iyakance samar da shi da kuma aikace-aikace mai fadi. To mene ne amfanin sa?
Alumina yumbura da yawa abũbuwan amfãni, kamar high inji ƙarfi, high taurin, low dielectric asarar a high mita, kuma saboda da fadi da tushen albarkatun kasa, in mun gwada da arha farashin da balagagge sarrafa fasaha, shi ne yadu amfani a cikin filayen lantarki. kayan lantarki, injina, yadi da sararin samaniya. Har ila yau, ya kafa babban matsayi a fagen kayan yumbura. An ba da rahoton cewa yumburan alumina sune yumbun oxide da aka fi amfani da su a duniya.
