Kurzbeschreibung (Abstract)
X-ray absorption near edge structure (XANES) measurements at the Si and N K-edges of ternary Si–C–N compounds are applied to analyze the changes of structural units owing to the thermally induced ceramization of silicon dicarbodiimide Si(N=C=N)2 at temperatures up to 1600°C. Samples synthesized below 800°C show an environment of silicon consisting of carbodiimide (N=C=N) groups. Further annealing leads to a crystalline phase, Si2CN4, which combines the structural units (Si–N–Si) and (Si–N=C=N). Recorded spectra of samples annealed at temperatures higher than 1200°C show the decomposition of Si2CN4. The material then transforms to a Si3N4–SiC composite material through an intermediate amorphous Si–C–N phase.
