摘要

以SHS法制备的细SiC填料粉为原料，以SiO2和MgO为粘结剂，在800 ~ 1300℃的温度下烧结成多孔陶瓷材料。考察了烧结温度对所制陶瓷的孔径、开孔率、抗弯强度和纯水渗透性等性能的影响。SiC基膜可以完全过滤掉D50 = 0.5 μm的固体SiC颗粒，经过多次过滤/再生循环后仍保持稳定的渗透性和物理力学特性。

Low-Temperature Sintering of SHS-Produced SiC-Based Porous Ceramics

Porous ceramic materials were sintered from fine SiC filler powder produced via SHS with binders SiO₂ and MgO at temperatures of 800–1300°C. The effect of sintering temperature on the properties of the resulting ceramics such as pore size, open porosity, bending strength, and pure water permeability was investigated. SiC-based membrane rejected completely solid SiC particles with D₅₀ = 0.5 μm while maintaining stable permeability and physical and mechanical characteristics after repeated filtration/regeneration cycles.

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.
