Toxicity pyrotechnic ingredients

Some of the important properties which are considered when choosing the ingredients for pyrotechnic formulations are density, hygroscopicity, melting and boiling points and decomposition temperatures, oxygen content of oxidizers, thermal conductivity of fuels and containers, nature of combustion products and toxicity etc. 

The extraction and ingredient recovery method provides an environmentnlly acceptable alternative to traditional open burning and destruction of pyrotechnics. CO2 solvent is nontoxic, nonflarnrnable, nonconosive, inexpensive, and does not generate arty additional toxic or hazardoirs wastes. The solvent is totally inert when it is corrfined, pressurized, and possibly heated in direct contact with an energetic propellant or mimition within a rocket...
