Barium Titanate: A Novel Perovskite Oxide Burning Rate Modifier for HTPB/AP/Al Based Composite Propellant Formulations

Abstract

Abstract In the present study, nano and micron‐sized barium titanate (BaTiO 3 ) were characterized and evaluated in HTPB/AP/Al composite propellant. Different compositions were prepared by incorporating BaTiO 3 from 0.5 % to 2 % in a standard composition. The BaTiO 3 reduces thermal decomposition temperature of ammonium perchlorate and also of standard composition. Other propellant processing and performance parameters like viscosity, mechanical and ballistic properties were also measured. The ballistic properties results revealed that there was more than 22 % and 12 % (at 6.86 MPa) enhancement in burning rate with 2 % nano and micro‐ BaTiO 3 , respectively.
