The Formula for Correlation between Porous Phase and Macro-mechanical Characteristics of the Material

Determination of the correlation of characteristics of consolidated body with content, size, distribution in matrix and shape factor of porous phase. The goal of the following paper is to determine formula for correlation between characteristics of ceramics and ceramic composite materials and porous phase, which is the weakest part of material. This will allow theorists and practicists to correctly choose and improve technologies and technical processes. According to the study and analysis of micro- and macrostructural, micro-and macromechanical of ceramics and ceramic composite materials, parameters of the formula was determined. Formula contains macromechanical properties. When detail is completely decomposed: mechanics on bending by three or four-point load, mechanics on shrinking, breaking, impact resistance. Morphologic characteristics: Porous phase content in the matrix and its distribution, size, shape factor of pores. Correlation of given factors with others structural characteristics, such as: crystal and glass phases. Novel determination of pore distribution factor is given. Created formula has collective nature and using it allows researchers and practicists to correctly plan and precisely preform all the positions of the technological production.
