Temperature Effect on the Synthesis of Gibbsite and Boehmite
To investigate the temperature dependency of gibbsite and boehmite formation, the Gibbs free energy change (Delta G) was calculated at different temperatures. Calculated Gibbs free energy shows a positive value at 323 K, and gibbsite formation is preferred. On the other hand, it shows a negative Delta G value at 371 K, and boehmite. formation is preferred. These predictions were characterized by transmittance electron microscopy and X-ray diffraction.
