Summary

SiC ceramics composites have potential application in heat exchangers due to their high thermal conductivity. In order to correlate the effect of processing on the heat transfer properties, analyses by Secondary Ion Mass Spectroscopy (SIMS) and Auger Electron Spectroscopy (AES) were performed. The impurity content obtained by SIMS-AES techniques was correlated with thermal conductivity, determined by the laser-flash method. Measurements were performed on commercial SiC-based ceramics as well as on Si-SiC composite materials prepared in controlled conditions. The role of transition elements is discussed.
