Do you observe (111) twins in BaTiO3 grains? They could form on doping with 3+ cations and trigger exaggerated grain growth. Check you microstructures for twins.

Ali Sari

It could be that the presence of iron (Fe3+, Fe2+) promotes the formation of a second phase which is formed in the matrix of BaTiO3.

Benyuan Ma

It may be an accelerated diffusion caused by doping. lower activation energy?
