An explosive particle-containing carrier material (24b) and a fully jacketed finished explosive material (33, 33') containing it, e.g., detonating cord, are produced in a high-speed continuous process by impregnating an absorbent carrier material such as cotton yarn (14) with a solution (12) of an explosive. Explosive particles (46) are precipitated from solution within the solution-impregnated carrier material (20) either by contacting the latter with a non-solvent fluid and/or subjecting it to flash evaporation under a vacuum. Rapid precipitation yields superfine explosive crystals (particles 46) within the carrier material (24b). Residual liquid non-solvent and/or solvent is removed from the carrier material, which may be encased in a plastic cover (38, 38') to provide a finished article (33, 33').
