Corundum cad oo leh budada aluminium oxide ee warshadaha sida alaabta ceeriin, ee arc ka dib heerkulka sare ee dhalaalay ee ka sarreeya 2000 digrii ka dib qaboojinta, ka dib markii la jajabiyo qaabeynta, kala-soocidda magnetic ee birta, shaandho ayaa loo qaybiyaa noocyo kala duwan oo cabbirka walxaha, alaabta la dhammeeyey waxay leedahay cufan cufan. engegnaanta sare, qayb qaab xagal fiiqan.Walxaha aan birta lahayn ee nadiifka sare leh, cadaanka sare, qallafsanaanta sare iyo cabbirrada walxaha kala duwan ee saxda ah.Badeecooyin taxane ah oo bacaad ah oo cabbirkoodu yahay: ku habboon warshadaynta dhoobada, agabka xaaqidda xabagta resin-ka iyo shiididda, polishing, ciid-qarxinta, shubidda saxda ah (maalgashiga shubista corundum gaarka ah) iyo wixii la mid ah.Qaybta ciidda iyo taxanaha budada ganaaxa: badiyaa loo isticmaalo soo saarista agabka refractory heerka sare ah.
