However,
It is a further objective to provide a solid pyrotechnic barium perchlorate made the propellant more hygroscopic Substance hi h h i i d at any temperature f om than barium nitrate and is considered less desirable from R or lower to approximately F. will Provide that standpomt although satisfactory otherwise. .Addihigh pressure gases for the purpose of actuating devices tional Teflon can also be substituted for the barium nitrate. which require high Pressure gases or liquids in order However, propellant samples for which this was done had less desirable physical properties. to function.
