Abstract

Highly porous Y₂O₃ based ceramic with nanoscale pores was prepared from an ultrafine mixture containing Y₂O₃ powder as a filler and additives (MgO, SiC, and SiO₂) as binders by combined use of compaction and thermochemical synthesis. The synthesized material was characterized by XRD/SEM and revealed to consist of Y₂O₃, Y₂SiO₅, MgO, and Si. Physical and mechanical properties such as specific surface area, density, compressive strength, and permeability were determined.

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
