在熔融FLiNaK盐中在650 ° C下在1、3和5atm的氩气气氛下对未涂覆的核石墨和各向同性热解碳（PyC）涂覆的石墨进行渗透研究。未包覆的石墨比PyC包覆的石墨表现出更明显的增重。扫描电子显微镜和压汞实验结果表明，具有PyC涂层的核石墨具有良好的抗熔盐渗透性能，这是由于其开孔率小。(C)2013爱思唯尔有限公司版权所有。
Infiltration studies were performed on uncoated nuclear graphite and isotropic pyrolytic carbon (PyC) coated graphite in molten FLiNaK salt at 650 degrees C under argon atmosphere at 1, 3 and 5 atm. Uncoated graphite shows weight gain more obviously than that of PyC coated graphite. Nuclear graphite with PyC coating exhibits excellent infiltration resistance in molten salt due to the small open porosity as conformed from scanning electron microscopy and mercury injection experiments.
