What was the observed effect of adding Aluminum Oxide ($ ext{Al}_2 ext{O}_3$) to ice on the sublimation rate compared to pure ice?
Answer
It had almost no effect on the sublimation rate.
Aluminum Oxide ($ ext{Al}_2 ext{O}_3$), characterized by strong scattering in the visible spectrum but low absorption there, demonstrated almost no change in the sublimation rate compared to pure ice, indicating that scattering is less influential than direct absorption by embedded impurities.
