Abstract: At the secondary fusion of Al, metal is lost because of its dispersion in the slag. Combining of individual drops of fused Al is hindered by Al₂O₃, which is practically insol. in KCl or NaCl. There is 15-20% of Al₂O₃ in slags after the fusion of Al waste with the flux. The removal of oxidn. layer from the surface of the metal is assocd. with the adsorption of solid particles of Al₂O₃ on the fused flux. The adsorption is strongly affected by the interphase force on the dividing line between the metal and solid Al₂O₃. It was detd. that the flux contg. chlorides did not have a favorable effect on the adsorption, while cryolite and CaF₃ in small concns. increased the adsorption.
