Metal/Fluorocarbon Pyrolants: VI. Combustion Behaviour and Radiation Properties of Magnesium/Poly(Carbon Monofluoride) Pyrolant

The performance of poly(carbon monofluoride) (PMF) (synonym: graphite fluoride) (CF x ) n , ( 1 ) as oxidizer in a fuel rich Mg based pyrolant (ξ(Mg)=0.45) is investigated. The radiance [W sr −1 ] under both static and dynamic conditions, the spectral radiant exitance [W cm −2  μm −1 ], the linear burn rate [mm s −1 ] and the mass consumption rate [g s −1 cm −2 ] have been determined. Calculations for enthalpy of anaerobic and aerobic combustion [kJ g −1 ] and for the equilibrium composition of the combustion products as well as combustion temperature are given. A mechanism for the reaction is discussed. The combustion product from Mg/(CF x ) n surprisingly reveals the formation of single walled carbon nanotubes (SWCNT) and “carbon nano carpet rolls” (CNCR).
