Abstract

Composition/structure of products formed upon frontal combustion of Si powder in gaseous carbon dioxide at P(CO₂) = 0.4–5.0 MPa were characterized by chemical analysis, XRD, and SEM/EDS. Combustion products were found to contain SiC, unreacted Si, and SiO₂. Our results may turn interesting to those engaged in fabrication of heat-resistant Si–O–C ceramics.

Si–CO 2系统中的SHS：燃烧产物的组成/结构

摘要

通过化学分析，XRD和SEM / EDS对Si粉在P（CO ₂）= 0.4–5.0 MPa的气态二氧化碳中进行正面燃烧时形成的产物组成/结构进行了表征。发现燃烧产物包含SiC，未反应的Si和SiO ₂。我们的结果可能对从事耐热Si–O–C陶瓷制造的人产生影响。
