摘要：

The oxidation behavior of biomorphic SiC based ceramics with different microstructure and composition was studied at 1450 degrees C in airflow for 50 h by thermal gravimetric analysis (TGA). SiC with amorphous, coarse grain, crystalline and fine grain crystalline microstructures as well as SiC-Si3N4 composite ceramics were processed from paper preforms by chemical vapor infiltration and reaction technique. The ceramics were characterized by X-ray diffraction and scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDX) before and after oxidation. The results show that the crystalline SiC with fine grain structure and SiC-Si3N4 composite ceramics show very good oxidation resistance at a temperature of 1450 degrees C.
