Thermochemical and kinetic studies of the acid attack of ...

The thermochemical and kinetic study of the attack of “B” type carbonate fluorapatites (B-CO 3-Fap) by a (19% w/w P 2 O 5) acid solution was performed using microcalorimetry at a temperature range between 25 and 55 °C and a pH 0.6. The results were processed iteratively in order to get the kinetic constant and the enthalpy of dissolution reaction.
