摘要
以廉价的TiC l4和BaC l2.H2O为主要原料在常压下通过溶胶沉淀一步法合成纳米晶BaTiO3。研究了钛液的水解浓度、碱浓度、反应时间等因素对直接合成纳米晶钛酸钡粉体的纯度和n(B a)/n(Ti)的影响。
In this paper, the new method of synthesis of barium fitanate is described, in which inexpensive TiCl4 and BaCl2· H2O are used as precursor. Influences of its purity, the solution hydrolyze of titanate, the different amount of NaOH addition and time of reaction on the direct synthesis of nanocrystalline barium titanate powder are researched.
