Oxidation of chromium

Effect of the [U(IV)/U(III)] ratio of fuel salt on selective chromium corrosion and tellurium intergranular cracking (IGC) of Hastelloy N alloy in the LiF-BeF2-UF4 salt mixture was investigated. The chromium corrosion of Hastelloy N alloy is caused by the oxidation of chromium on the alloy surface by reaction with UF4.

The modification of chromium oxide added into iron oxide by co-precipitation method significantly prevents the sinterring of iron and iron oxide during repeated redox cycles. The activity of 4 redox cycles is stable and the H2/Fe ratio is almost the same with theoretical value.
