摘要：
A process for producing porous ceramics with controlled microstructure. Colloidal suspensions of decomposable polymeric microspheres of substantially the same size and shape, and aluminum oxide particles are consolidated to form a compact. The compact is heated to decompose the microspheres to leave pores, and to sinter the compact, to form a porous ceramic body in which the pores are substantially spherical and are evenly distributed and noncontiguous throughout the ceramic matrix and with strength comparable to its dense state.
