National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Passivation of the Pyrotechnic Fuels Titanium and Titanium Hydride in Oxidative Environments.

SAND780264C

Publication Date	1978
Personal Author	Quinn, R. K.
Page Count	15
Abstract	The chemical and physical properties that govern the performance and sensitivity of pyrotechnic materials were studied. The oxidation of Ti and TiH surface shows that electrochemical oxidation and air oxidation produce similar oxide coatings. The electrochemical process produces no extraneous results or products. There are no solvent effects on the electrochemical or surface analytical results. The first 20-50 A of Ti and TiH/sub x/ electrodes exposed to air or electrolyte solution are identical. The oxide on or near the surface would be mixed and not totally oxidized to TiO sub 2 . A full range of oxides is observed from TiO to TiC sub 2 . This observation is true for powder and bulk Ti and TiH/sub x/, as well as films. At least eight intermediate oxides are known to exist in the region between Ti sub 2 O sub 3 and TiO sub 2 . Reduced or substoichiometric titanium oxides would be semiconducting, whereas purely stoichiometric TiO sub 2 would be insulating. (ERA citation 04:003950)
