Abstract

Analysis of the SiC-SiC joint and its brazing mixture has been performed using a Raman spectroscopy microprobe technique. A careful mapping of the sample clearly shows the spatial distribution of the chemical species close to and within the joint. A different distribution of the 4H and 6H α-SiC polytypes, grown during the brazing process, was observed inside the joint. The furthermore, identification of the bands related to the Nowotny phase was also possible.
