Ama-floating beads angamabhola angenalutho anombala we-fly ash angantanta phezu kwamanzi. Amhlophe qhwa, mancane futhi angenalutho, futhi anesisindo esincane. Ubuningi bawo bungu-720kg/m3 (osindayo), 418.8kg/m3 (olula), kanti usayizi wezinhlayiya ucishe ube ngu-0.1 mm, ubuso buvaliwe futhi bubushelelezi, ukuhanjiswa kokushisa kuncane, kanti ukuphikiswa kungama-≥1610℃. Ukwakheka kwamakhemikhali kwama-floating beads ikakhulukazi yi-silicon dioxide ne-aluminium oxide. Inezici eziningi njengezinhlayiya ezincane, ezingenalutho, isisindo esincane, amandla aphezulu, ukumelana nokuguguleka, ukumelana nokushisa okuphezulu, ukuvimbela ukushisa, ukuvimbela ukushisa kanye nokuvimbela ilangabi. Isetshenziswa kabanzi kwenye yezinto zokusetshenziswa zemboni yokuvimbela ukushisa.
