A modified alternative for high purity barium titanate nanoparticles production

In this research, a modified, cost efficient and quick sol-gel procedure was used for preparation Of Tehran, Iran BaTiO3 nanoparticles. By a modified selection of precursors and utilization of optimized precursors ratio and controlling the hydrolysis conditions, finer BaTiO3 nanoparticles were synthesized in shorter period of time and lower temperature contrary to results obtained in previous researches. In this research the sol is prepared only in 90 minutes but other researchers prepared their sols in more than 8 h. Moreover barium titanate nanoparticles have been prepared after calcination in 800 °C for 1h but similar results show the presence of carbonate phases in composition of prepared nanopaticles. The proposed procedure seems to be more preferable for mass production.
