Study on the Hydrothermal Synthesis of Electronic Ceramic Material Barium Titanate

论述了用H2 TiO3 和Ba(OH) 2 ·8H2 O为原料水热合成钛酸钡的方法 .讨论了反应温度和反应时间、H2 O和Ba(OH) 2 ·8H2 O与H2 TiO3 的配比及煅烧温度和煅烧时间对产品质量的影响 .所制取的产品纯度高、粒径小 .

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.
