In addition, H2 is extremely sensitive to spark initiation, and can cause premature detons when ammo is being handled, is in-tube during launch, or is being steam-cleaned for reloading, purposes. A parallel reaction involves the release of NH3, which can combine with metals such as Cu in the presence of nitrates to form such extremely shock sensitive compds as tetramino cupric nitrate (Ref 17). To obviate these effects, desiccants such as silica gel may be added to the extent of 0.5% (Ref 12)... 

Tetramino Cupric Nitrate [or Tetraammine copper(II)nitrate]. [Cu(NH3)4](N03)2 mw255.73 N 32.87% purple monocl cryst. Sol in ammonia and w. Prepn is by addn of aq amm hydroxide to an aq soln of cupric nitrate with stirring at 5°. 

Phillips (Ref 2) conducted an investigation of the impact sensy increase of Amatol mixts contg this compd as an accidental prod of the combined action of NH4 ion, air and moisture on metallic Cu at high temp, or by the action of basic nitrates of Cu on metallic Cu at normal temps. He reports that in a 50/50 mixt of TNT/ Tetramino-cupric nitrate, the impact sensy is 14" as compared to 19" found for 50/50 Amatol. Phillips accordingly recommended that no Cu or Cu alloys be used in any eqpt which may come in contact with Amatol during its manuf...
