摘要

在活性粘合剂的参与下，采用压实法和技术燃烧法相结合的方法合成了一种基于 Sc2O3 的高效节能多孔陶瓷材料。利用 XRD、SEM 和 EDA 方法发现，该材料具有高度发达的多层次微观结构形态，其基础是 Sc2O3 和凹凸棒石 Sc2Si2O7。材料孔隙空间的主要特征（孔隙率、孔径、比表面积、渗透性等）是通过汞孔测定法和其他方法确定的。

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

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.
