Continuous weight‐change measurements were used to determine the vaporization kinetics of Na 2 SO 4 from 900° to 1200°C in 150 torr O 2 . Simple evaporation of the sulfate was indicated. An activation energy for vaporization of 71 kcal/mol was calculated. Vaporization results obtained for Na 2 SO 4 on oxide substrates indicated an Na 2 SO 4 ‐Cr 2 O 3 reaction; however, no Na 2 SO 4 ‐ZrO 2 reaction was observed.
