Production aspects are considered for preparing porous ceramic based on α-Al2O3 using the effect of zonal compaction during powder workpiece sintering of very fine combustion products in air of flaky aluminum powder PAP-2 particles. It is shown that formation of a porous structure in sintered material proceeds by a local breakage mechanism through boundaries of aggregates with formation of pores between agglomerates, and also due to occurrence of a closed intergranular pore system. Properties of the ceramic obtained are: density 2.45 g/cm3, total porosity 39%, open porosity 30%, closed porosity 9%, the and ultimate strength in bending 50 – 60 MPa.
