The sintering and grain growth behaviour of NiO-doped BaTiO3 in air are investigated in the present study. The solubility of NiO in BaTiO3 is determined by measuring the lattice constant of BaTiO3 as a function of NiO content. The solubility is around 0.13wt% as sintering temperature ranges from 1250 to 1330 C. The densi®cation of BaTiO3 is retarded due to the solution of NiO. Possible mechanism is proposed. The existence of residual NiO inclusions also reduces the densi®cation rate. The adding… CONTINUE READING
