Corrosion characteristic of AlN, Y2O3, Er2O3 and Al2O3 in Flinak for molten salt blanket system
Abstract
For liquid breeder blanket system using molten salts, tritium barrier, anti-corrosion barrier, tritium recoverysystemandheatexchangermakeimportantroles.Especiallyintheheatexchanger,thetritiumpermeationfrom primary coolant loop to secondary coolant loop mustbe inhibited by the tritium barrier for safety. Todevelopit,itisessentialtooptimizechemicalstability ofthebarriermaterialagainstmoltensalts.Inthepresent study, the corrosion on bulk specimens of AlN, Y2O3Er2O3and Al2O3in Flinak was investigated. Thestatic corrosion tests were performed for 230 and 1010 hours using these specimens with high purity Flinak at600C in Ar atmosphere. Weight measurement and surface analysis of the specimens were carried out beforeand after the corrosion test. Chemical analysis of the Flinak also did before and after the corrosion test. AlNshowed corrosion resistance, even though the surface was slightly oxidized and corroded. Er2O3, Y2O3andAl2O3dissolved into Flinak. In Er2O3corrosion, Zr in the matrix as an impurity might affect on the corrosion.TheY2O3 corrosionwassmall.Theweightlossduetothecorrosionwasaffectedbythebreakingofthespecimens with porous structure. And the Al2O3corrosion was large. The surface structure changed to roughsurface. These corrosion behaviors agreed withprediction based on thermodynamic evaluation.
