摘要

In the present work, the hot corrosion behavior of ZrB2-SiC-graphite (G) composite in different media at 900 and 1000 degrees C was investigated in detail. The results indicated that the ZrB2-SiC-G composite became slightly corroded in NaCl molten salts owing to the ZrB2 phase of the ZrB2-SiC-G composite being oxidized by oxygen molecules dissolved in the NaCl molten salts. However, the ZrB2-SiC-G composite underwent more severe corrosion in Na2SO4 molten salts, owing to the complex oxidation and sulfidation reaction of the ZrB2-SiC-G composite exposed to oxygen molecules and decomposition products of Na2SO4 at high temperature.
