Abstract
A method is provided for making blast explosive molding powder. According to an aspect of the invention, energetic solids and a metal powder are suspended in a bulk phase fluid. Lacquer is added to an energetic solids and metal powder suspension to achieve a super-saturated solution. Final granulation of the super-saturated solution is optimized to form a fluidized metallized energetic molding powder. The fluidized metallized energetic molding powder is distilled to remove an organic solvent component of the lacquer, which is reclaimed through distillation. The bulk phase fluid is decanted to recover a wet metallized energetic molding powder. The bulk phase fluid is reclaimed through distillation. The wet metallized energetic molding powder is dried to form a dry metallized energetic molding powder. This method is especially useful in making insensitive enhanced blast explosive molding powders with high metal powder content.
