Abstract:
The soak test of four kinds of graphite sealing material was performed in N2O4 to verify the compatibility of graphite material and N2O4. According to the test results, the reason to influence the sealing performance of graphite material is analyzed in the aspects of the graphite porosity, impregnating resin, graphite substrate material, graphite element and microstructure. Analysis result indicates that the graphite impurities and microstructure has important influence on N2O4 resistance
