Shrinkage kinetics in sintering laminated orthortropically porous powder materials

Technological developments in recent years have created suitable conditions for producing the so-called anisotropically porous powder materials. Their anisotropy forms as a result of directional distribution of pores having the form d continuous capillaries (channels) which penetrate through the porous matrix in the given directions. These materials are biporous: anisotropic porosity, formed by channels, is combined in them with the isotropic porosity of interchannel walls formed by powder particles from which the matrix is produced.
