Study of the Dissolution Rate of Iron in N204 by the Use of Radioactive Tracers

Abstract

The objective of the research was to obtain data to assess the probability of N2O4 iron induced flow decay occurring in liquid propulsion feed systems. Data were obtained for the rate of dissolution of iron in N2O4, for the solubility limit as a function of temperature, and for the effects on the rate and solubility of adding small amounts of the impurities H2O, NOC1 and NO. A radioactive tracer technique was developed to make the necessary measurements at the low concentrations encountered. The results obtained followed basically a solubility-type behavior. The mechanism suggested from the results is one in which N204 reacts initially with the iron to form a surface layer of iron nitrate whereupon the iron nitrate dissolves in N2O4.
