摘要：

We have demonstrated a new synthesis of ceramics with porosity-grading microstructure, being achieved by applying high acceleration to ceramics during sintering. The acceleration was generated by high-speed rotation of ceramics, which allows pressing materials gradually along the radius of rotation. The origin of microstructure has been explained quantitatively from the basis of sintering kinetics, in which non-uniform shrinkage caused by a centrifugal pressure has been taken in account.
