摘　　要：以ＴｉＣｌ_４、ＢａＣ１_２·Ｈ_２Ｏ、ＫＯＨ、ＮａＯＨ为原料，在ｐＨ＝１２～１３、反应温度９０～１００℃、反应时间１ ～２ｈ下经凝胶——水热反应合成钛酸钡，经有关厂家进行了半导化试验，借助于ＸＲＤ、高分辨率电子 显微镜及化学分析，证明产物达到纳米级钛酸钡水平．A Method of synthesis BaTiO_3 through gel - hydrothermal synthesis from TiC1_4, BaCl_2. 2H_2O, KOH reactants at pH = 12 ~ 13,90 ~ 100, 1 ~ 2hr. was conducted. The products were detected through semiconducting experiment, and were investigated by means of XRD SEM and chemical analysis. The results show that the Product were high quility Semi - conductor material with nanometer size.
