The nanostructured c and a alumina powders were synthesized by sol-gel and co-precipitation methods,and properties of the powders were studied by XRD, SEM,TEM, BET and FTIR. The results showed that both c and a phases were formed in the lower temperature in precipitation method compared to sol-gel. The size of spherical aalumina synthesized by sol-gel was 10–15 nm, whereas the sample prepared by co-precipitation yielded nearly spherical and hexagon a-powder with particle size of 10–50 nm.At 750 ℃ the resulting powder prepared by co-precipitation exhibited larger surface area (206.2 m2/g) compared to sol-gel (30.72 m2/g), hence it is recommended for catalytic and sensing applications.
