CHARACTERISTICS AND MORPHOLOGY OF THE PORE SPACE OF SYNTHETIZED HIGHLY POROUS Sc2O3 CERAMIC MATERIALS

Abstract

An energy-efficient synthesis of highly porous ceramic materials based on Sc2O3 was carried out using a combination of compaction and technological combustion methods with the participation of active binders. Using XRD, SEM, and EDA methods, it was found that the material has a highly developed multilevel microstructure morphology based on Sc2O3 and tortveitite Sc2Si2O7. The main characteristics of the pore space of the material (porosity, pore size, specific surface area, permeability, etc.) were determined by mercury porosimetry and alternative methods.
