Abstract
An energy-efficient synthesis of highly porous ceramic materials based on Sc2O3 was conducted using a combination of compaction and technological combustion methods with the participation of active binders. Using XRF (x-ray phase analysis), SEM (scanning electron microscopy), and EDA (energy dispersive analysis) methods, it was found that the investigated material has a morphology based on Sc2O3 and thortveitite Sc2Si2O7 that is highly developed, multi-level, and microstructural. The basic characteristics of the material’s pore space (porosity, pore size, specific surface area, permeability, etc.) were determined by means of mercury porosimetry and alternative methods.
