A method for determining the maximal size of through pores of ceramics from the temperature of the water crystallization onset

摘要

A new method for determining the maximal size of through channels of porous materials from the temperature of the water crystallization onset (crystallization-onset method) is proposed. The comparative measurements of sizes of through pores of ceramic filters by this method and by the method of determining the point of bubble growth are performed in accordance with GOST (State Standard) 50516-93. The correlation dependence between the overshoot pressure drop of the first bubble and the temperature of the water crystallization onset in the pore space of a ceramic filter is plotted.
