Abstract
A solid explosive composition is made by curing a mixture of a 20-50% by weight of a liquid matrix, 50-80% by weight of an essentially anhydrous inorganic chlorate or perchlorate salt, and 0-15% of a nitrate salt after transferring said mixture to a mold. The matrix can include 50-84% by weight of a non-explosive liquid fuel selected from the group consisting of polyhydric alcohols, lower aliphatic alcohols, ketones, and hydrocarbons; 0-15% by weight of a nitrate oxidizer salt; 0-15% by weight water; 0-15% by weight of a thickener; and 0-5% by weight of an acid.
