Abstract: CuO has been doped solely and together with BaO and SiO 2 into barium titanate by mixing and calcination. X-ray diffraction showed that the sample doped by CuO-BaO has stable second hexagonal phase while the samples doped by CuO, CuO-SiO 2 were of a pure perovskite phase. For CuO-BaO doping, the Curie temperature was decreased accompanied with higher ε max; while for CuO doping and CuO-SiO 2 codoping, the Curie temperature was increased with ε max decreased. The difference can be explained considering that Cu 2+ ion could not only incorporate into the BaTiO 3 lattice, but also assemble in the boundary phase when CuO was doped solely. Besides, the mechanisms of CuO doping and SiO 2 doping could happen at one time.
