2011, Thermochimica ActaCitation Excerpt :The use of UN as a civilian or military explosive is not advantageous partly because of its corrosive and acidic properties, and possibly due to its degradation property producing nitric acid. The decomposition of UN at much higher temperatures was studied in the literature describing important parts of the decomposition mechanism [7–11]. Our study has found that, at 100 °C over a period of 48 h, urea nitrate degraded into a mixture of solids; ammonium nitrate, urea and biuret [6].
Degradation mechanism and thermal stability of urea nitrate below the melting point
2011, Thermochimica ActaCitation Excerpt :The use of urea nitrate as a civilian or military explosive is not acceptable because of its corrosive acidic properties that may cause instability in some cases and possibly due to its degradation properties. Decomposition processes of urea nitrate were studied by quantum chemistry calculations [3,6] and evaluated by thermal analysis as reported in a few papers [7–10]. We have recently shown the complexity of the decomposition mechanism at high temperature up to 360 °C and determined the associated kinetic parameters [11].
