摘要：

Super thermites Al/PbO, Al/CuO and Al/Bi2O3 were prepared by ultrasonic dispersion process using nano-Al, nano-PbO, nano-CuO and nano-Bi2O3 as the raw materials, and the products were characterized by XRD, SEM-EDS and IR. DSC thermal analysis method was employed to evaluate compatibility of three kinds of super thermites with some double-base propellant main components. On the bases of characterizations, the effects of three super thermites on the combustion properties of double-base(DB) propellant were investigated. The results indicate that All PbO, Al/CuO and Al/Bi2O3 have good compatibility with nitrocellulose (NC), nitrocellulose/nitroglycerine (NC/NG) and N-nitro dihydroxy ethylamine dinitrate (DINA), hut they are slightly sensitive with cyclotrimethylene trinitramine (RDX) and 1, 3-dimethyl-1, 3-diphenylurea (C-2). DB propellant containing three kinds of nano super thermites showed excellent performance of combustion, which indicates that super thermites have tremendous potential superiorities in application of DB propellant.
