Sharaxaad Gaaban:

Gamma alumina waa budo qalafsan oo cad oo leh qaybinta cabbirka walxaha isku midka ah, nadiifin sare, iyo kala firdhisanaan aad u fiican. Waxay leedahay dusha sare oo gaar ah, heerkul sare oo aan firfircoonayn, iyo dhaqdhaqaaq sare. Waa alumina firfircoon; daloolsan; adkaanta sare iyo xasilooni cabbir wanaagsan. Waxaa si weyn loogu isticmaali karaa xoojinta iyo adkaynta caagadaha kala duwan, caagadaha, ceramics, alaabta refractory iyo alaabta kale, gaar ahaan si loo hagaajiyo cufnaanta, siman, qabow iyo caabbinta daal kulul, adkaanta jabka, caabbinta gurguurta iyo alaabta wax soo saarka polymer sare ee dhoobada. . Caabbinta xirashada ayaa si gaar ah cajiib ah.
