Abstract Wetting of fused silica by molten aluminium at temperature of 800 to 1000° C and 3×10−5 Torr was dependent on the formation of a reaction zone by redox reactions. The reaction zone consisted of three layers. It was postulated that reactions proceeded by interdiffusion of Si2+, Al+, Al2+ and Al3+: the layer adjacent to the metal drop was primarily AlO stabilized by a solid solution of SiO; and adjacent to fused silica, a spinel of AlO and Al2O3 stabilized by SiO. On cooling these dissociated into Al, Si and θ-Al2O3 and/orα-Al2O3.
