The present report explores the use of cross‐polarization (CP) and single‐pulse magic angle spinning nuclear magnetic resonance (MAS‐NMR) as well as normal and surfaceenhanced Raman spectroscopy (SERS), in concert, for characterizing highly crystalline polymorphic silicon carbide ceramics. The combined use of these techniques provides a wealth of information regarding bulk, near‐surface, and surface speciation. Both Raman and SERS are promising techniques for fracture surface characterization of these systems. The application of CPMAS‐NMR and SERS to the study of ceramics is reported for the first time in this investigation.
