ABSTRACT:
Method and apparatus are described for applying a wax or plastic coating to phosphor grains to be added to explosives for tagging purposes. The coating is obtained by spraying from a nozzle a homogenous mixture of molten coating material and phosphor grains and permitting the droplets thus formed to solidify during free fall through a cooling medium such as air. The coated phosphors thus obtained when incorporated into an explosive render the mixture less sensitive to friction and impact than the corresponding mixture employing uncoated phosphors.
