摘要：

The influence of the initial grain morphology on the anomalous grain growth in donor-doped barium titanate has been studied. The results show that powders with aspherically shaped grains exhibit a much lower critical donor-dopant concentration, inhibiting anomalous grain growth during sintering, than powders with equisized spherically shaped grains and a similar, or even a lower, initial specific surface area.
