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 ($$1.7 kN\ x\ \tfrac {s}{kg}$$).


 * 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.
