摘要
The present study shows the effect of porosity on the dynamic elastic moduli of partially dense yttria (Y2O3). This article reveals that the sound velocities and the elastic moduli of the porous samples depend not only on density, but also upon the reciprocal of the initial particle and agglomerate size. These findings explain some of the variation in the elastic moduli found especially, but not only, for highly porous yttria.
