Description
In this investigation, Cr2O3 ceramics with different grain sizes were prepared and tested in supercritical water (SCW) environment at 650°C /25 MPa for 200 hours. The results show that the stability of Cr2O3 in SCW was affected by its grain size. In addition, various amounts of CeO2 were added to Cr2O3 to examine the effect of CeO2 on the corrosion behaviour of the Cr2O3 based ceramic under SCW condition. These Cr2O3-based ceramics were exposed to an SCW environment at 650°C/ 25 MPa for up to 600 hours. The results showed that adding a proper amount (≤ 5 wt. %) of CeO2 increased the corrosion resistance of Cr2O3-based ceramics in SCW. (author)
