Alumina (Al2O3) powder was synthesized by simple wet-chemical precipitation method. The phase
study was done using XRD confirming the FCC phase. FTIR showed the presence of Al-O vibrations.
Particle size analysis (PSA) confirmed the presence of particles in the range of 300 nm. The EDX
confirmed the presence of Al and O elements in the samples only and no impurity elements. SEM
exhibited the ultrafine nature of the particles. The tape casting of Al2O3 nanoparticles was carried out
with suitable organic ingredients. Based on the trials, the best composition for alumina tape casting
was optimized. The SEM of green alumina thin sheet resulted in good surface behaviour. Optimized
composition may be used for fabricating thin Al2O3 based electrical components for application in
electronics industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
