Abstract : The heat of formation of gibbsite, from alpha-alumina and water, has been redetermined by solution calorimetry in hydrofluoric acid at 75C. A value of - 13.3 plus or minus 0.6kcal was found. The heats of combination of selected light element double oxides have also been determined by solution calorimetry in hydrofluoric acid at 75C. In the case of the double oxides that contained alumina, gibbsite was used as a reference compound. (Author)
