Re: re re ANFO
Ammonium nitrate (NH4NO3) decomposes exothermally at 210 °C in H2O (steam) and N2O (laughing gas). N2O is a better oxidizer than pure oxygen.
So a mixture of ammonium nitrate and organic matter is a powerful explosive. It is however known to explode spontaneously.
N2O in itself is stable. In 1914 Robert H. Goddard patented a rocket apparatus powered by N2O and gasoline.
