Intergranular space, specific surface area, grain size distribution and distribution of macro, meso and micropores of multiphase microstructure in active microalloyed multifunctional ceramics

As a complex multiphase heterogeneous system in solid state, multifunctional active microalloyed alumo-silicate ceramics has an inhomogeneous structure with intergranular space, which is reflected in a number of structurally sensitive properties. A very complex intergranular space and numerous inter...

description As a complex multiphase heterogeneous system in solid state, multifunctional active microalloyed alumo-silicate ceramics has an inhomogeneous structure with intergranular space, which is reflected in a number of structurally sensitive properties. A very complex intergranular space and numerous interactions between individual phases and grains create new boundaries and an even more complex space with much smaller micrograins, which are formed by grain fragmentation by dislocations displacement. In addition to reducing macro and meso porosity, densification of intergranular space increases the number of micro pores. Intergranular surface area and volume are considered as dislocation space. Quantitative metallography method was applied to determine grain size distribution using software for automatic analysis. Specific surface tests and pore distribution were performed on special samples of multifunctional ceramics. Standard methods for determining specific surface area of samples in vacuum were used. Obtained results, which were relevant in terms of theoretical and practical implications, confirmed that multifunctional active microalloyed ceramics had a developed surface with significant number of meso and micro pores. Due to constancy of grain fragmentation process, there were significant changes in micromorphology and all multifunctional properties, as well as movement of dislocations, which made a significant contribution to contemporary research in this field.
