Guanidine nitrate



Guanidine nitrate is a high energy fuel used in some gas generator and solid rocket propellant applications.

Overview

Guanidine nitrate has chemical formula C(NH2)3NO3. It has been used as a monopropellant in the Jetex engine for model airplanes. It is attractive because it has a high gas output, low flame temperature, and non-toxic combustion products. It has a relatively high monopropellant specific impulse of 177 seconds (1.7 kN\ x\ \tfrac {s}{kg}).[1]

  • Chemical Dangers:
    • May explosively decompose on shock, friction, or concussion.
    • May explode on heating.
    • On combustion, forms toxic and corrosive fumes including nitric acid and nitrogen oxides.
    • The substance is a strong oxidant and reacts with combustible and reducing materials.
  • Routes of Exposure: The substance can be absorbed into the body by ingestion.
  • Inhalation Risk: A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
  • Effects of Short-Term Exposure: The substance is severely irritating to the eyes and the skin.
  • Stability: May explode if heated. May be shock sensitive.
  • Toxicology: Toxic if inhaled, swallowed or absorbed through the skin.
