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.

A method of preparing a cast solid explosive product for use as a primer and a small diameter explosive, consisting essentially of the steps of:
- a) obtaining a liquid matrix consisting essentially of at least one liquid, water-soluble polyhydric alcohol of low volatility;
- b) mixing at ambient temperature the liquid matrix with dry sodium perchlorate oxidizer salt in proportions to form an initially pourable matrix-salt mixture which is not sensitive to a No. 8 blasting cap but which will cure with time and increase in sensitivity during curing to form a solid that can be detonated with a No. 8 blasting cap, said curing taking place without deliberate crosslinking of the matrix-salt mixture;
- and
- c) allowing the matrix-salt mixture to cure to form a solid explosive product that can be detonated with a No. 8 blasting cap.
