| KRATKA VSEBINA | Methods of stereological study are of great importance for structural researchof electronic ceramic materials includingBaTi03-ceramic materials. The broad application of ceramics, based on barium-titanate, in advanced electronics nowadays demands a constant research of its structure, that through the correlation structureproperties, a fundamental in the basic materials properties prognosis triad (technology-structure-properties), leads to further prognosis and properties design of these ceramics. Microstructure properties of BaTi03ceramic material, expressed in grains' boundary contact, are of basic importance for electric properties of this material, particularlythe capacity. In this paper, a significant step towards establishing control under capacitive properties of BaTi03-ceramics is being done by estimating the number of grains contact surfaces. Defining anefficient stereology method for estimating the number of BaTi03-ceramic grainscontact surfaces, we have started from a mathematical model of mutualgrains distribution in the prescribed volume of BaTi03-ceramic sample. Since the real microstructure morphology of BaTi03-ceramics is in some way disordered, spherical shaped grains, using computer-modelling methods, are approximated by polyhedra with a great number of small convex polygons. By dividing the volume of BaTi03-ceramic sample with the definite number of parallel planes, according to a given pace, into the intersection plane a certain number of grains contact surfaces are identified. According to quantitative estimation of 2D stereological parameters the modelled 3D internal microstructure is obtained. (Abstract truncated at 2000 characters). |
