Abstract:

Bismuth/zirconium gallate (Gal-BiZr) was synthesized from gallic acid, bismuth nitrate, and zirconyl nitrate firstly, and characterized by elemental analysis, X-ray fluorescence (XRF), and Fourier transform infrared (FTIR) spectroscopies. The thermal behavior and decomposition mechanism of Gal-BiZr in a temperature-programmed mode were investigated by thermogravimetric (TG) analysis, differential scanning colorimetry (DSC), and condensed phase thermolysis/FTIR techniques. The decomposition products of Gal-BiZr are Bi2O3, ZrO2, and C. Samples of propellants containing Gal-BiZr were prepared by extrusion technology, and the effect of Gal-BiZr on double-base (DB) propellant combustion properties was investigated. Gal-BiZr exhibits good catalytic behavior in the combustion of DB and Hexogeon (RDX)- CMDB propellants.
