摘要：

Uniform coating of beta-silicon carbide (beta-SiC) was formed over a graphite pellet through slurry-based silicon coating followed by in situ reaction at 1873 K (1600 A degrees C). The coated pellet was exposed to molten lead-bismuth eutectic (LBE) at 1173 K (900 A degrees C) in static condition for 200 h. Weight loss measurement, X-ray diffraction, and secondary electron microscopy-energy-dispersive spectroscopy confirmed that the SiC coating could effectively prevent molten LBE from attacking the inner graphite material.
