The dispersion procedure of preparing nitrocellulose ball propellant containing combustion catalyst was described and effects of concentration of nitrocelloluse （NC）,dissolving time,volume ratio of water/solvent (RH₂O/RAC)and stirring rate onproperties of final products were investigated.The results show that the pseudodensity（ρb）and medium diameter(D₅₀) increase with the solution concentration and dissolving time of NC.The increase of RH₂O/RAC and stirring rate led to increase of ρb and decrease of D₅₀.
