Industrial Applications of Power X-ray Diffraction Analysis to the Ti-Hx-KCIO4 Pyrotechnic System by Don B. Sullenger,Ralph R. Eckstein,Richard S. Carlson Pdf
Powder X-ray diffraction techniques were extensively applied in a pyrotechnic materials development project involving the TiHx-KClO4 system. They were utilized in the evaluation of locally synthesized TiHx materials to assist in evolving the best method for preparing such hydride materials. Once that method was fixed, X-ray diffraction made a contribution towards material specification for the project in that it afforded baseline data for TiHx and KClO4 starting materials, and especially in the determination and detailed characterization of the phases present in their various blends. Such methods concurrently afforded routine support for other project teams investigating container and bridgewire corrosion phenomena, material and device handling and storage factors, alternative milling and blending effects, particle size classification consequences, reaction product identification, etc. A 12-kW rotating anode X-ray generator was used to good advantage in the effort. It yielded adequate diffraction photographic exposures from tiny specimens in a few minutes time, and thus, made practicable some investigations which otherwise would not have been possible. Aside from the immediately practical support provided for the project a reference pattern was obtained for the nonstoichiometric fluorite-structured [gamma]-TiH2-y phase which proved superior to any found in the literature. Also a quality lattice parameter as a function of stoichiometry curve was deduced from the repeated phase analyses. Detection limits of minor amounts of various substances often encountered in the course of the project were also assessed.
