摘要：
The compactability and sinterability of alumina granules prepared by spray freeze granulation drying (SFGD) and spray drying (SD) were compared. The strengths of the granules made by SFGD and SD, densities of the green bodies and sintered bodies, pore size distributions of the green bodies, internal structures and strengths of sintered bodies made from SFGD and SD granules were evaluated. The strength of SFGD granules was lower than that of SD granules. The lower granule strength of the SFGD granules was advantageous to form a uniform structure without inter -granular pores in the green body, resulted in higher density and strength of the sintered body.
