INVESTIGATION OF MK 25 MOD 2 STARTER COMPOSITION
NAVAL AMMUNITION DEPOT CRANE IN
Pagination or Media Count:
A study is made on various chemical and physical characteristics of the Mk 25 Mod 2 Starter Composition, which is an oxygen deficient siliconlead dioxide - cupric oxide system. A scheme for chemical analysis, already provided in RDTR No. 27, is reviewed. Physical phase changes and chemical reaction mechanism of the compvents, and of the mixture as a whole are explored by differential thermal analysis and thermogravimetric analysis. The principal chemical reactions are considered and the theorectical thermodynamic values compared with experimental values. Behavior characeristics, such as sensititity, stability, heat of reaction, ignition point, and other available information are included in a Pyrotechnic Data Collection Sheet.
