Abstract: Of the following five reactions, the enthalpy changes of the first three reactions were calorimetrically determined, respectively. Combination of these results with the values from literature led to the recommended values of the enthalpy changes of the five reactions as follows: Al(OH)3(s)=(1/2) γ Al2O3(s)+(3/2)H2O(g) 101.89±1.20 kJ·mol -1 γ AlOOH(s)=(1/2) γAl2O3 (s)+(1/2)H 2O(g) 46.60±1.00 kJ·mol -1 γ Al 2O 3(s)= αAl2O3 (s) Al(OH)3 (s)=γ -18.53±1.00 kJ·mol -1 AlOOH(s)+H 2O(g) Al(OH)3 (s)=(1/2) α 55.29±1.20 kJ·mol -1 Al2O3 (s)+(3/2)H2O(g) 83.36±1.20 kJ·mol -1
