| Abstract | ||
| This paper deals with the preparation of Alumina by sol-gel technique through the hydrolysis of aluminum ion mixed with the glucose as a surfactant and converting it to gel by ammonium hydroxide in aqueous media. The resulting sol composed of particle is draying to become a transparent gel. The freshly prepared gel is heated at 700°C for 2hrs to obtain alumina ( )particles. The obtained particles are found to be γ-alumina particles with high porosity, Their characteristics are determined by LPSA, XRD, SEM, TEM and BET techniques. The results show that the particles are pure alumina, nano-sized=20nm, spherical shape, high surface area=210 /gm. | ||
