Figures

FIG. 1.

A schematic diagram of the gap test experiment. The charge was 5 mm in diameter, formed of a tapped granular bed.

Image of FIG. 2.
FIG. 2.

Typical ESEM and optical images of each class 1 batch. They are shown in order from highest to lowest sensitivity The field of view in the optical images is across and for the ESEM images it is across. The most sensitive materials have the fewest internal voids, but also the sharpest edges and corners.

Image of FIG. 3.
FIG. 3.

ESEM images of typical class 5 crystals. They are shown from most to least sensitive, starting at the top left and continuing clockwise. Many dimples can be seen on the surfaces of the 5a material, the most sensitive. As sensitivity decreases, the surfaces get smoother.

Tables

Generic image for table
Table I.

Summary of critical gaps and input pressures. All samples are listed from most to least sensitive within each size class.

Generic image for table
Table II.

Optical microscopy results for class 5 and class 1 material.

Generic image for table
Table III.

Available data from mercury porosimetry for all size classes. Both the measured and calculated values (for spheres) of specific surface area (SSA) are shown and also their ratio. The plateau scale is the pore size at which the plateau in the cumulative surface area measurement was reached, i.e., the scale below which there is no significant surface roughness. Within each size group, samples are shown from most to least sensitive. The percentage of HMX found in each sample is also shown.

Generic image for table
Table IV.

The angle of repose and free-poured density for each batch and the uncertainty in the measurements. Within each size class, the batches are shown with the most sensitive at the top of the list and the least sensitive at the bottom.

Generic image for table
Table V.

Summary of the morphological features of the class 5 RDX investigated. Samples are listed from most to least sensitive.

Generic image for table
Table VI.

Summary of the morphological features of the class 1 RDX investigated. Samples are listed from most to least sensitive.
