ABSTRACT:
A process for the manufacture of water gel explosives comprising mixing microspheres to be expanded in a concentrated solution or eutectic melt containing part of the ingredients of the finished explosive such that the microspheres can be expanded at a temperature at which there is no danger of explosion of the mixture. In particular, the solution or ment has an oxygen balance in which it poses no safety risk at the temperature required for the expansion of the microspheres. Thereafter, at a lower temperature the remaining components of the explosive including the sensitizer are mixed with this premix containing the expanded microspheres.
