Shenhai e fakamoʻoni fakaʻauha
ʻOku fakafehokotaki ʻa e ignition ʻo e efu ʻalaminiume ki he hauhau mo e mao ʻi he ʻatakai.
Ko ha efu, aluminum’s surface activity is heightened, taki ki ha tali ʻaki e vai ʻoku ne ʻomi e ʻea vela mo e kasa fakapaaki ʻo e. ʻOku totonu nai ke tanaki ʻa e kasa fakapaaki ʻo e ko ʻeni ki ha huʻanga pau, ʻe lava ke hoko ʻa e afi fakatuʻupakee. Subsequent to ʻa e afi, relighting aluminum powder with oxygen leads to an even more vigorous exothermic reaction at elevated temperatures.
