摘要
A novel propellant composition comprises granules of ammonium nitrate and nitrocellulose, in the ratio between 0.22 and 1, the granules being coated with at least one layer of nitrocellulose containing powdered aluminum, the aluminum being in the proportion between 1 and 5 percent by weight of the compositions. The composition exhibits improved water resistance, lower water absorbency and ignition is facilitated. According to one embodiment, nitrocellulose is replaced by polyvinyl nitrate in the proportion of up to 40 percent based on the weight of the mixture of polyvinyl nitrate and nitrocellulose.
