ABSTRACT

BaCO3 crystals with various morphology were prepared using precipitation, hydrothermal and ligand-assisted methods. An irregular structure of BaCO3 microparticle was obtained by simple precipitation method from Ba(NO3)2 and Na2CO3 in aqueous solution. Hexagonal pyramidals of BaCO3 were synthesized using a hydrothermal method between Ba(NO3)2 and urea. Hexagonal rods of BaCO3 were also synthesized using the ligand-assisted hydrothermal method. The aspect ratio of BaCO3 hexagonal rods was increased with the concentration of ligand.
