In hydrothermal reaction process, reversible reaction was accompanied between γ-al 2 O and AlO(OH), and hydrothermal reaction temperature, hydrothermal reaction time and CH COOH concentration had an effect on the crystal structure, surface chemical property, surface area, pore characteristics and crystal morphology of the AlO(OH) nano colloid particles. In this study, it was investigated to the hydrothermal reaction condition of the AlO(OH) nano colloid for using catalyst support, heat resisting agent, adsorbents, binder, polishing agent and coating agent. The crystal structure, surface area, pore volume and pore size of the platelet AlO(OH) nano colloids were investigated by XRD, TEM, TG/DTA, FT-IR and N 2 BET method in liquid nitrogen temperature.
