Phase formation in porous liquid phase sintered silicon carbide:
چکیده انگلیسی
The reaction products of the interaction of Y2O3 with SiC and the resulting microstructures were analysed using model experiments. The effects of the influence of different sintering atmospheres, namely Argon and Ar/CO, as well as vacuum and different temperatures have been investigated. The phase formation was determined by X-ray diffraction (XRD) and can be explained on the basis of thermodynamic calculations. Depending on the sintering conditions, silicides or yttrium carbides can be formed in addition to stable oxides, which can result in the decomposition of the samples after sintering. Reactions between SiC and Y2O3 during sintering can be suppressed successfully if an Ar/CO atmosphere is used.
