Spherical powders (ball or rolled, compact or porous)
Apart from basic nitrocellulose, double base powders contain - as energetic component- nitroesters, usually nitroglycerine (10-38%). The powders further contain small quantities of chemical stabilizers or other similar compounds as it is with single base powders. Double base powders can be of higher energetic content than single base powders. Their calorific value varies - according to the type - within 3, 800 - 5, 200 kJ/kg. From the users's point of view, their ballistic and other properties are usually more interesting than these of single base powders. Powder grains can be in the form of cylinders, tubes, flakes, discs, ribbons or spheroids.
