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

Overview

Guanidine nitrate is the salt formed from guanidine and nitric acid. It has the 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 and low flame temperature. It has a relatively high monopropellant specific impulse of 177 seconds ($1.7\; kN\; x\; frac\; \{s\}\{kg\}$). [1000 lbf/in² (700 kPa) chamber pressure, 14.7 lbf/in² (101 kPa) exit pressure, shifting equilibrium theoretical performance]

Hazards:
*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.
*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.
*Harmful if inhaled, swallowed or absorbed through the skin.
