Superfine alumina waa walxo ceeriin ah oo muhiim u ah dhoobada shaqaynaysa.Superfine alumina budada xz-L20, cabbirka walxaha 100 nm, midab cad, 99% ee nuxurka adag.Waxaa lagu dari karaa noocyo kala duwan oo biyo ku salaysan, gudaha resins saliid ku salaysan, dareerayaasha iyo caagadaha heerka dheeraadka ah ee 3% -5%, taas oo si weyn u hagaajin karta adkaanta walxaha ilaa 6-8H ama xataa ka sareeya.
Hadhuudhka Q-A1203, oo leh dusha kiimikaad hooseeya iyo iska caabin heerkul sarreeya, ma aha alumina qallalan ee firfircoon, mana laha wax dhaqdhaqaaq ah.Waxay leedahay iska caabin kulayl xoog leh, formability wanaagsan, wajiga crystalline deggan, engegnaanta sare iyo xasilloonida cabbir wanaagsan, oo waxaa si ballaaran loo isticmaali karaa in xoojinta iyo toughening ee caagadaha kala duwan, caag, ceramics, alaabta refractory iyo alaabta kale, gaar ahaan si loo hagaajiyo cufnaanta. dhammayn, daal kulul iyo qabow, adkaanta jabka, caabbinta gurguurta ee ceramics iyo caabbinta xidhashada alaabta polymer.
