Study on the Hydrothermal Synthesis of Electronic Ceramic Material Barium Titanate

In this paper, the hydrothermal synthesis of barium titanate from Ba(OH) 2·8H 2O and H 2TiO 3 was described. The reaction temperature and time, the ratio of H 2O and Ba(OH) 2 to H 2TiO 3, calcining temperature and time,which influence the quality of product were studied. Our investigation shows that the purity of prepared barium titanate is high and particle diameter is small.
