Though materials containing fluorine atoms can act as oxidizers, most fluorine compounds are gases or Hquids at ambient temperatures and hence cannot be used as oxidizers in pyrolants. However, some solid fluorine compounds are utilized as oxidizer components of energetic pyrolants. 

The selechon of fuel components to be mixed with oxidizer components is also an important issue in the development of pyrolants for various applications. Metal particles are used as fuel components to develop small-scale pyrolant charges as deployed in igniters, flares, and fireworks. Non-metal particles such as boron and carbon are used to formulate energetic pyrolants. Polymeric materials are commonly used as fuel components to develop relatively large-scale pyrolant charges, such as gas generators and fuel-rich propellants. 

The incorporation of magnesium particles into fluorine-containing polymeric materials, such as polyfluoroethylene (Tf) or vinyUdene fluoride hexafluoropropene polymer (Vt), generates energetic pyrolants. The magnesium particles are oxidized by fluorine molecules eliminated from these polymers to produce high-tempera-ture magnesium fluoride.
