Abstract

The resistance of sapphire and sintered Al2O3 to corrosion by K vapor was examd. at 1173 and 1373 K. As predicted from thermodn. calcns., Al2O3 is not stable under exptl. conditions. The K-b-alumina that formed had a preferential orientation with the c axis parallel to the surface. No protective layer against further corrosion was formed. CaO as a dopant had no effect on the corrosion reaction. [on SciFinder (R)]
