摘要：

The formation of microporous alumina from various gibbsite samples has been studied under conditions of controlled residual pressure and decomposition rate. The information obtained from thermal analysis, nitrogen adsorption, scanning calorimetry, and X-ray diffraction are consistent with a model in which the reaction interface advances parallel to the basal plane of the crystal, drilling" micropores at the place of the "structural channels" of the gibbsite lattice and where the width of the micropores is controlled by the desorption stage. © 1979."
