Abstract
Alumina has been widely used in biomedical applications due to its superior chemical, mechanical, and wear properties, and exhibits good biocompatibility. However, its limited use in hip and knee replacement applications is due to its low fracture toughness and bio-inertness. This study focuses on the synthesis and characterization of alumina nanopowders using a cost-effective sol-gel method using aluminum isopropoxide, as a precursor. The powders obtained after drying the gel in an oven were calcined at 800 oC for 1 hour in an electric furnace to produce the alumina nanopowder. During this process, parameters, such as temperature, pH, and stirring time, were carefully controlled to obtain the final product. X-ray diffraction, SEM, and TEM analysis were used to characterize the phases, composition, particle size, and morphology of alumina nanopowders. As a result, SEM and TEM analyses in conjunction with XRD data indicate that high-purity alumina nanopowders can be synthesized via the sol-gel process.
