Evaluations of accumulated and incremental pore size distribution for different areas of depth indicate size pore percentage increase from 3 to 5 mm for the 50 mm deep area from the hot face. Such results are to be ascribed to SiC and C oxidation resulting in refractory microstructure perme- Fig. 10.
