How does the physical density of an explosive mixture influence the detonation velocity of a high-order explosive chain?

The detonation velocity of a high-order explosive is the speed at which the shock front travels through the material. This velocity is directly influenced by physical density, which is the mass per unit volume of the explosive mixture. In most high explosives, increasing the density initially increases the detonation velocity because the molecules are packed more closely together, allowing the chemical reaction to transfer energy more efficiently from one layer to the next throu....
