Mendeleev Russian Chemical Engineering University, Moscow, Russia aut Causes of anomalous crystal growth in sintering ceramics after formation of closed pores began [Elektronische Daten] [A. Belyakov] The rapid growth of crystals after formation of closed pores begins in a sintered intermediate product is explained with the premises of the chemistry of crystals with defects and synergistics. The change in the structure of an infinite cluster of open pores as they are converted to closed pores decreases the concentration barrier of vacancies that prevent diffusion transfer through the boundaries and growth of the crystals. The nonisometric shape of the crystals and high rate of diffusion mass transfer promote the anomalous growth. The easy deformability of the boundaries of the crystals can lead to slight adjustment of their crystallographic orientations and joining of the crystals, which ensures their anomalously rapid growth.
