US Patent:

8636861, Jan 28, 2014

Filed:

Dec 29, 2010

Appl. No.:

12/980571

Inventors:

Daniel Stec, III - Long Valley NJ, US
Amy Wilson - Blairstown NJ, US
Brian E. Fuchs - Hackettstown NJ, US
Neha Mehta - Succasunna NJ, US
Paula Cook - Succasunna NJ, US

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

C06B 25/34

US Classification:

149 92, 149 1992, 1491096

Abstract:

Secondary crystalline high explosives are disclosed which are suitable for filling very small volume loading holes in micro-electric initiators for micro-electro-mechanical mechanisms (MEMS), used as safe and arm (S&A) devices. The explosives are prepared by adding the such a high explosive to an aqueous first volatile mobile phase, adding such a high explosive to a non-aqueous second volatile mobile phase, mixing the first and second volatile mobile phases and then loading the combined phases into the MEMS device and allowing the aqueous and non-aqueous solvents to evaporate depositing the high explosive. Enhanced adhesion between the deposited high explosive and enhanced rheological properties can be obtained by adding a polymeric binder to both mobile phases.
