纳米级热敏电子陶瓷材料钛酸钡的合成

Synthesis of Nanometer Thermal Sensitive Ceramic Material BaTiO_3

以TiCl4，BaCl2-2N2O，KOH，NaOH为原料，在pH值10～12、反应温度60～150℃、压力0．1～0.35MPa、反应时间1～4h下经凝胶－结晶转变会成钛酸钡，经有关厂家进行了半导化试验，产物借助于XRD，TEM及化学分析，证明产物达到纳米级钛酸钡水平．

A Methed of synthesis BaTiO3 through gel-to-crystallite conversion from TiCl4, BaCl2.2H2O,NaOH, KOH rcactants at pH=10-12, 60-150℃,14 h,0.1-0.25 MPa was conducted. The products were detected through semi-conducting experiment, and were investigated by means of XRD. TEM and chemical analysis. The results show that the product wer high quility semi-conductor material with nanometer size.
