Abstract:

THE OXIDATION OF Al occurred linearly with time in the presence of mercuric halides and water vapor. The slope of this linear curve was constant at any particular relative humidity and increased with an increase in relative humidity. Additional data to be used in conjunction with all the previous oxidation-rate measurements are presented. Several new saturated-salt solutions were used to give relative humidities different from those used previously. The slopes of the oxidation-rate curves are tabulated along with the relative humidities obtained from the saturated-salt solutions. Rate curves are presented for experiments at 100, 92.9, 74.9, 54.2, and 26.6 RH. The influence of the relative humidity upon the oxidation rate is noted. The lazy - S curve is similar to one previously reported, but additional points are included which change the shape somewhat. The rapid increase in oxidation rate is still noted in the 60-75 RH. range.
