Abstract :
In this work, nanoparticles of titanium dioxide (TiO2) were synthesized by means of TiCl4 as precursor. Effects of alcohol type, calcination, gelatinizing time and microwave exposure on the particle size, morphology,
crystallinity and particle phase are studied using XRD
patterns and SEM images. Results showed that alcohols
such as ethanol increased the particle size; calcination
increased the particle size and improved the crystallinity of
particles. Microwave exposure of particles resulted in
smaller particles; adding water increased the impact of
microwave. Effect of microwave exposure in rutile phase
formation is also observed during this study.
