ZrC-SiC基陶瓷作为氟化物候选材料的适用性进行了评估。在熔融FLiNaK盐（LiF-NaF-KF：46.5/11.5/42摩尔%）中在850 °C下进行ZrC-SiC复合材料的浸没腐蚀。结果表明，ZrC-SiC基陶瓷比ZrC陶瓷具有更好的耐腐蚀性能。ZrC-40 SiC陶瓷相对于ZrC的质量损失为50%。这种碳化物表现出最小的腐蚀攻击，因为在熔融氟化物中的溶解有很强的抵抗力。XRD结果与失重法和SEM结果一致。ZrC-SiC基陶瓷的腐蚀行为受杂质的影响，特别是氧含量。氧和/或氧离子参与了陶瓷的腐蚀。碳化物陶瓷的腐蚀主要是由于陶瓷中的C4−。该离子被熔融盐中的氧化剂或杂质氧化成元素C。C的加入可以抑制熔盐的腐蚀，从而提高碳化物陶瓷的耐腐蚀性。
The suitability of ZrC–SiC-based ceramics was assessed as candidate materials for fluoride. An immersion corrosion with ZrC–SiC composites was performed in molten FLiNaK salts (LiF–NaF–KF: 46.5/11.5/42 mol%) at 850 °C. Results indicated that ZrC–SiC-based ceramics were more corrosion resistant than the ZrC ceramic. ZrC–40SiC ceramic exhibited 50% weight-loss to ZrC. This carbide exhibited minimal corrosion attack because of strong resistance to dissolution in molten fluorides. Furthermore, XRD results were consistent with weight-loss and SEM results. The corrosion behavior of ZrC–SiC-based ceramics was affected by impurities, particularly oxygen content. Oxygen and/or oxygen ion participated in corrosion of ceramic. Corrosion of carbide ceramics is mainly due to C4−in ceramics. This ion is oxidized to elemental C by oxidants or impurities in the molten salt. The addition of C may inhibit corrosion of molten salts and thus improve the corrosion resistance of carbide ceramics.
