Area-Perimeter Relation of the Grains in Stabilized Cubic Zirconia

摘要

Based on the observation that the ratio of the perimeter, P, to the square root of the area, A , of the grains for a given material is nearly constant, it is suggested that the grain shape may be treated as a regular polygon with a non-integral side number. Examining the variation of P/A~(0.5) -ratio with sintering holding time may provide useful information for sintering dynamics. Further analysis suggests that the P/A~(0.5)-ratio may be a potential parameter for studying the grain-boundary effect in polycrystalline materials.
