Preparation and Characterization of Porous Alumina

More Information
  • Received Date: December 31, 1899
  • Revised Date: December 31, 1899
  • The porous alumina with different poroperties, porous alumina film and power porous aluminum were respectively prepared by two type methods. The porous alumina film on Al foil was prepared at different anodic voltage oxidation time by quadratic anodic oxidation. The most suitable experiment condition is quadratic anodic oxidation time is 7 h and voltage is 40 V. There are three methods that can prepare porous alumina powder, heating method, hydro-thermal method, sol-gel method. Alumina was characterized by XRD, thermal analysis, N2 adsorption desorption and TEM, the biggest surface area is the one which is prepared by sol-gel method, it is 263 m2/g, it also has concentrated pore size distribution.
