Silicon Carbide Ceramics: The Science and Engineering of a High-Performance Material for Extreme Environments si3n4 ceramic
1. Basic Framework and Polymorphism of Silicon Carbide 1.1 Crystal Chemistry and Polytypic Diversity (Silicon Carbide Ceramics) Silicon carbide (SiC) is a covalently bound ceramic material composed of silicon and carbon atoms arranged in a tetrahedral coordination, developing a highly stable and robust crystal latticework. Unlike numerous standard porcelains, SiC does not have a single,
