Abstract : It was demonstrated that isomorphous and phase rule concepts can be used as a theoretical guide for obtaining valuable new oxidizer 'alloys'. New synthesis techniques were explored to facilitate preparation of NH4ClO4-KClO4 and NH4ClO4-NH4NO3 'alloys' on an expanded scale. It was found that it was considerably more difficult to make the latter type of homogeneous mixed crystals. This was due to the theoretically predicted lack of ideality of the behavior of this salt pair in water. It was shown that introduction of NH4CLO4 into the crystal lattice of NH4NO3 tends to increase the latter's thermal stability and decrease its sensitivity to moisture. At the same time NH4NO3 appears to reduce the impact sensitivity of NH4ClO4. These are desirable effects from a propellant and explosive standpoint. (Author)
