Abstract:

Zirconium gallate (Gal-Zr) zirconium/ copper gallate (Gal-ZrCu) were synthesized firstly by using gallic acid, zirconyl nitrate and copper nitrate as raw materials, and was characterized by elementary analysis, X-ray fluorescence diffraction ( XRF ), Fourier transform infrared ( FTIR ) spectroscopy and TG-DTG technique. The sample of propellants containing Gal-Zr and Gal-ZrCu were prepared by extrusion technology, and the effects of Gal-Zr and Gal-ZrCu on combustion properties of DB/ CMDB propellants were investigated. The results show that Gal-Zr and Gal-ZrCu are excellent and environmental-friendly catalysts, and they possess good catalytic effect on combustion of DB propellant. However, the results indicate that Gal-Zr or Gal-ZrCu is not ideal.

Key words: physical chemistry, zirconium gallate, zirconium/ copper gallate, double-base propellant, RDX-CMDB propellant, combustion property, catalytic activity
