摘要：

The coarsening behavior of large seed particles during the sintering of BaTiO3 ceramics has been investigated. At 1350 degreesC, the grains are faceted, and the seed particles grow extensively, At 1380 degreesC, however, the grains are spherical, and coarsening of the seed particles is limited. The observed difference is discussed in terms of the growth mechanism and the atomic structure of the interfaces.
