Effect of Cr3+ on the corrosion of SiC in LiF-NaF-KF molten salt was investigated. Cr3+ in LiF-NaF-KF molten salt can aggravate the corrosion of SiC. The thickness of corroded region in salt with Cr3+ is much larger than that in pure salt. The corroded region is composed of Cr2C3, Cr7C3, Cr2O3, and graphitic carbon. Corrosion induced by Cr3+ should be attributed to reactions of Cr3+ with SiC.
