Microstructural comparison of porous oxide ceramics from the system Al2O3-ZrO2 prepared with starch as a pore-forming agent

Popis výsledku v původním jazyce

In this paper examples of microstructures of porous oxide ceramics prepared by traditional slip casting (TSC) and starch consolidation casting (SCC) are shown and results obtained using different microstructural characterization techniques are presented;Archimedes method (open and total porosity), shrinkage measurement, mercury intrusion porosimetry (pore size distribution) and microscopic methods - optical microscopy with microscopic image analysis (pore size distribution) and scanning electron microscopy (detailed investigation of the local microstructure). In particular, microstructures are compared for porous ceramics from the system Al2O3-ZrO2 prepared with rice and corn starch. It is shown that the maximum values of the total porosity of porousceramics prepared with starch as a pore-forming agent were approx. 50%. A major finding by using SEM with respect to starch-produced porous ceramics is the existence of pore fillings in the form of small sintered ceramic shells inside the
