【Abstract】 In this paper,a oxidizer-ammonium nitrate used in the composite propellants is introduced. It has two important properties: polymorphic phenomenon and hygroscopicity which seriously influences the use of ammonium nitrate in some fields. Consequently, we have to investigate and find out about polymorphic phenomenon and hygroscopicity of the ammonium nitrate to increase quality of the products.更多还原
