Tabular aluminas grit e faia i le Al2O3, pe a maeʻa mea, olo ma fausia, faʻafefeteina i le ogaumu vevela maualuga liliu i le α- Al2O3.
E lelei le fa’afefeteina o le vevela ma le malosi tele o le vevela o le vevela. Tabular alumina tioata fa’asolosolo foliga ipu ipu, e fa’ateleina ai le malosi fa’ainisinia o vaega; fausaga totonu e tumu i pores tapuni, maualuga bulk density, maualalo porosity manino ma vai absorption, e faaitiitia ai le aofaiga o le suavai toe faaaogaina gaosiga; Fa’atasi ai ma mea lelei fa’aletino e pei o: maualuga refractoriness, tete’e te’i vevela sili ona lelei, fa’aitiitia maualalo ma lelei fa’avevela mamafa malosi ma isi I le taimi nei, maualuga-mama e aloese mai le fa’aleagaina o masini.
