Alumina Superfine waa walax ceeriin ah oo muhiim u ah dhoobada shaqaynaysa. Budada alumina Superfine xz-L20, cabbirka walxaha 100 nm, midabka cad, 99% ka mid ah waxyaabaha adag. Waxaa lagu dari karaa noocyo kala duwan oo resins biyo ku salaysan, oo ku jira resins saliid ku salaysan, dareereyaal iyo cinjirro heer lagu daray oo ah 3%-5%, taas oo si weyn u hagaajin karta adkaanta walaxda ilaa 6-8H ama ka badan.
Q-A1203 oo leh dusha sare ee kiimikada oo hooseeya iyo iska caabin heerkul sare, ma aha alumina qalalan oo firfircoon, mana laha wax dhaqdhaqaaq kicin ah. Waxay leedahay iska caabin kulayl oo xooggan, qaab wanaagsan, marxalad kristal ah oo deggan, adkaansho sare iyo xasillooni cabbir wanaagsan, waxaana si ballaaran loogu isticmaali karaa xoojinta iyo adkeynta balaastikada kala duwan, caagga, dhoobada, agabka adkeysiga iyo alaabada kale, gaar ahaan si loo hagaajiyo cufnaanta, dhammaystirka, daalka kulul iyo qabowga, adkaanta jabka, iska caabbinta gurguurta ee dhoobada iyo iska caabbinta xirashada walxaha polymer.
