Abstract
THE influence of adulterating grit on the impact and friction sensitivity of a number of explosives has been shown to be considerable1. It is generally agreed that grit sensitizers act through modification of conditions necessary to produce frictional hot-spots, and that this process is influenced to a large extent by the hardness of the grits. Although detailed hardness data are now available for many of the common grits2, little or none exists for the explosives themselves.
