PP-IV-4Δ(λ) were measured in a 400-700 nm wave length range. Spectral resolution of the instrumentwas 2 nm, scanning pitch – 20 nm, incidence angle – 60°. Four-zone averaging measurementswere applied.Fig. 2. The dependence of the oxide film thickness on the time of In-Ga melt keeping withoutAl (white points) and with Al (black points).As the presented dependencies show, the oxide film forms quite rapidly. The mechanismof aluminium dissolution is most likely determined by the transfer of the dissolved Al in theAl-In-Ga system to the melt-water interface followed by the formation of aluminiumhydroxide and hydrogen.403
