Formation of a porous structure for biporous materials connected with volume changes during sintering

A feature of porous structure formation in biporous materials is a significant change in pore dimensions without an equal change in the material as a whole, and this depends on pore anisotropy. It is also shown that during sintering of biporous materials shrinkage of micropores affects the formation of the pore structure in a macroporous system. There is a significant difference between biporous and monoporous materials.
