Abstract

Abstract: In order to explore the feasibility of in-situ superfine dispersion of water-soluble oxidizer in microporous ball propellant, the oxidizers with various concentrations are added to aqueous solution in the process of preparing the microporous ball propellant, which enables the oxidizers to disperse uniformly by filling them in the internal pores of ball propellant. Scanning electron microscope, X-ray diffraction and X-ray photo electron spectrometer are used to characterize the ball propellants which contain various oxidizers and dispersed oxidizer particulates. The result indicates that the micro-porous ball propellant which is filled with uniformly dispersed oxidizer particulates could be prepared by adding water-soluble oxidizers with concentration of less than 30%. The mean particle size is not greater than 3 μm. The fill rate of oxidizer in microporous ball propellant increases observably with the rising of oxidizer concentration. The superfine dispersion of water-soluble oxidizer in microporous ball propellant could be achieved by means of in-situ dispersing.Key

Key words: microporousballpropellant, watersolubleoxidizer, superfinedispersion, in-situ
