Abstract: A means for reducing or eliminating the erosive burning which takes place ring the burning phase of solid propelled rocket motors which have a large length-to-diameter ratio and/or slow-burning propellants is disclosed. The means comprises incorporating into the solid propellant, in limited percentages (0.1-1.0%), a silicate selected from talc, kaolinite, kaolin, muscovite mica, and feldspar. The silicate additive is effective for composite or double-base solid propellant compositions. The solid composite propellant compositions can vary widely in formulation ingredients to include numerous ballistic modifiers; however, the general formulation for a composite propellant contains in addition to the silicate, a high solids loading of an inorganic oxidizer such as ammonium perchlorate, a polybutadiene binder with curatives and crosslinking agents, and optional metal fuel, preferably aluminum. The polybutadiene can have carboxyl- or hydroxyl-terminal groups.
