Questions are considered connected with use in ceramic technology of ultrafine powder raw material with agglomerated particles. It is shown that presence of agglomerates in nanopowders unavoidably leads to formation in sintered material of structural defects in the form of residual porosity and microcracks. Data are provided for a quantitative dependence of pore structure characteristics for a powder compact on the content of agglomerated particles and the connection of pore structure characteristics with sintering kinetics and the properties of the sintered material obtained.
