"The physical characteristics of dense ammonium nitrate prills were examined. The density was found to be 1.52 grams per cubic centimeter, and from this the specific surface was calculated for the size fractions of interest in the investigation. Theoretical loading densities were calculated for between 26.0 and 47.6 percent voids.
The explosive properties of discrete particle size fractions were investigated. The equation by Clark was found to predict the detonation velocity of the sizes smaller than 8/20 mesh. The equation by Cook could not be applied to dense prilled ammonium nitrate. The possibility of a very oxygen negative condition existing with the largest prills was investigated.
Tests showed that dense prilled ammonium nitrate-fuel oil mixtures became more sensitive as their particle size decreased. The number of prills contacting the primer was found to be approximately a constant for the particle size ranges investigated. This was attributed to the effect of "hot-spots" on initiation of detonation"--Abstract, page ii.
