Knudsen evaporation experiments were made on gadolinium sesquioxide from 2350° to 2590°K. Two sets of Knudsen cell data yielded average values of 468.7 ± 0.8 and 471.0 ± 0.5 kcal/mole for the assumed evaporation reactionThe results indicate that the evaporation coefficient may be much less than one.
