Ablation experiments of SiC-based materials have been conducted systematically in our laboratory. In this study, physico-chemical phenomena of ablated SiC-based material in high-speed and high-temperature air plasma-jets were investigated. In the experiments, ablation gases spouted out from the SiC-based materials were observed by a high-speed video camera, In addition, radiation from the SiC-based ablation products was measured by a CCD with several kinds of narrow band-pass filter. We obtained spatial distributions of atomic Si lines and CN molecular bands in the ultraviolet wavelength region. Furthermore, spectroscopic measurements in the representative points of the flowfield were performed to investigate the radiative characteristics of SiC-based ablation products in detail.
