Abstract: Experimental measurements of the ablation properties of the fine ceramics SiC and Si_3N_4 are performed in an atmospheric high-temperature argon plasma jet. The effective heat of ablation is measured for the heat flux of 1.2~2.6×10^4 kW/m^2. It is found to be about 2×10^4kJ/kg for Si_3N_4 and 5~8×10^4kJ/kg for SiC. In addition, features of the ablated surface of the materials are observed with the aid of an electron microscope, and on this basis, the mechanism of the ablation is discussed.
