摘要：

Bulk densities and their sintering shrinkages of different radius compact disks cut from a CIP compact were measured to investigate the influence of compressibility of granules in compression test on density distribution in a CIP compact. Two kinds of granules, Al2O3 and SiC, with different compressibility were used. Bulk densities of compact disks increased with increasing the radius of disks and sintering shrinkages decreased with increasing the radius. All these things made it clear that there was density distribution in radial directions of CIP compacts. SiC compact by CIP produced much lager difference of density in radial direction, compared with Al2O3 compact. It seemed reasonable to suppose that the compressibility and surface condition of granules had an influence on producing differences of density in radial direction.
