Abstract: Synthesis of high purity barium titanate powders by the catecholate process was performed by reacting catechol as a complexing agent with titanium tetrachloride in toluene to yield titanium complex, H2[Ti(C6H4O2)3], which then reacted with suspension of barium carbonate in deionizes water to yield barium titanate catecholate. The complex was isolated in solid form by freeze – drying. Subsequent decomposition to crystalline barium titanate was achieved by heating the freeze – drying complex from 600 ° C to 900 ° C with increment of 100 degrees for 3 hours. The physical and chemical properties of barium titanate were investigated. Phase transition of barium titanate powders was also studied.
