Power of explosives

The power of explosives is determined in a conventional manner. The most usual test is the determination of the lead block expansion and the rate of detonation. In some countries the crushing of lead and copper cylinders is determined. [Pg.438]

In Anglo-Saxon countries a test in a ballistic mortar is also used. Tests for explosive power should be repeated occasionally for inspection purposes in production. [Pg.439]

There are many other ingredients that are added to explosive compositions which in themselves are not explosive but can enhance the power of explosives, reduce the sensitivity, and aid processing. Aluminium powder is frequently added to explosive and propellant compositions to improve their efficiency. Ammonium nitrate (NH4N03) is used extensively in commercial explosives and propellants. It is the most important raw material in the manufacture of commercial explosives and it also provides oxygen in rocket propellant compositions. Some of the properties of ammonium nitrate are presented in Table 2.22. [Pg.47]

The power of high explosives can be expressed in terms of their force and has the units of kJ g 1 or MJ kg 1, which is the same units as the power of explosion. The force can be calculated from Equation 5.25, where F is the force constant, n is the number of moles of gas produced per gram of explosive, R is the molar gas constant and Te is the temperature of explosion in Kelvin. [Pg.101]

The force and power of explosion are in fact the same, as shown below in Equation 5.27 and Equation 5.28. [Pg.101]
