A New Glycothermal Process for Barium Titanate Nanoparticle Synthesis

Abstract

Barium titanate (BaTiO 3 ) nanoparticles were synthesized at the low temperature of 80°C through a glycothermal reaction using Ba(OH) 2 ·8H 2 O and amorphous titanium hydrous gel as precursors and a solution of 1,4‐butanediol and water as solvent. This processing method provides a simple low‐temperature route for producing BaTiO 3 nanoparticles, which could also be extended to other systems. It is demonstrated that the size of BaTiO 3 particles can be controlled by reaction conditions, such as reaction temperature and various volume ratios of 1,4‐butanediol/water.
