Heterogeneous precursors for SiC particles were synthesized from viscous phenolic resin and tetraethyl orthosilicate with hastening ethanol removal process in a concentrated state. In the pyrolysis products, spherical carbon domains with diameter of several micrometers were embedded in the SiO 2 -C matrix. After the carbothermic reduction process at 2073 K, SiC-C spheres were obtained with an SiC yield of ϳ80%, while the carbon domains acted as templates of the SiC-C spheres with complete disappearance of the SiO 2 -C matrix area. After the carbon burned out, some of the spheres possessed a hollow structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
