I-alumina egqwesileyo yinto ebalulekileyo kwi-ceramics ezisebenzayo. I-superfine alumina powder xz-L20, ubungakanani be-particle 100 nm, umbala omhlophe, i-99% yomxholo oqinileyo. Ingongezwa kwii-resin ezahlukeneyo ezisekelwe emanzini, ngaphakathi kwee-resin ezisekelwe kwi-oyile, izinyibilikisi kunye neerabha kwinqanaba elongeziweyo le-3%-5%, elinokuphucula kakhulu ubulukhuni bezinto ukuya kuthi ga kwi-6-8H okanye nangaphezulu.
I-Grain Q-A1203, enomgangatho wayo ophantsi weekhemikhali kunye nokumelana nobushushu obuphezulu, ayisiyo-alumina eyomileyo esebenzayo, kwaye ayinamsebenzi wokutsala. Inokumelana nobushushu okunamandla, ukwakheka okuhle, isigaba sekristale esizinzileyo, ubunzima obuphezulu kunye nozinzo oluhle lobukhulu, kwaye ingasetyenziswa kakhulu ekuqiniseni nasekuqiniseni iiplastiki ezahlukeneyo, irabha, iiseramikhi, izixhobo ezichasayo kunye nezinye iimveliso, ngakumbi ukuphucula uxinano, ukugqitywa, ukudinwa okushushu nokubanda, ukuqina kokuqhekeka, ukumelana nokuqhekeka kweeseramikhi kunye nokumelana nokuguguleka kwezinto zepolymer.
