“…All the diffraction peaks can be identified as the crystalline AACH (JCPDS card 042-0250). The chemical reaction occurs as follow [11] The pH value of the initial solution has great effect on the size and morphology of the hydrothermal products. The SEM images of precursors a, b and c, which are synthesized in different pH values are shown in Fig.1(B),(C),(D).…”

Abstract-NH 4 Al(OH) 2 CO 3 precursors were prepared using Al(NO 3 ) 3 and NH 4 HCO 3 as raw materials. The structural, morphological, and porous properties of the materials were investigated by BET, X-ray Diffraction (XRD), and Scanning Electron Microscope (SEM).The morphology and aspect ratios of resulting AACH nanoparticles were significantly influenced by the pH values in the preparation of solid precipitates.There were two kinds of morphology present, nanofibers and nanoplates. After thermal treatment at 550 o C in air for 4 hours, the morphologies of the nanostructures werewell preserved while the crystal structure was converted to γ-alumina.
