A method of forming a gas generant according to various implementations includes the steps of providing a mixture of copper nitrate and water and adding melamine and guanidine carbonate to the copper nitrate and water mixture at room temperature. Next, the melamine, guanidine carbonate, copper nitrate, and water mixture is mixed and heated to form a melamine nitrate, guanidine nitrate, basic copper nitrate, and water mixture. The heating and mixing step may be performed at a temperature in the range of 50 C. to 60 C. for at least 20 minutes. Then, the melamine nitrate, guanidine nitrate, basic copper nitrate, and water mixture is dried to form the gas generant comprising melamine nitrate, guanidine nitrate, and basic copper nitrate. The method may further comprise a step of adding an additional fuel, an additional oxidizer, or an additive. Also disclosed is a gas generant made by the method described above.

The present invention is a red-light-emitting composition based upon a potassium periodate oxidizer formulation, which is useful as the illuminant in the US military's M662 40 mm red star parachute projectile, and which composition is composed of readily commercially available ingredientsingredients that are environmentally friendly. Further, the subject inventive potassium periodate formulation provides significant enhanced illumination and safety versus the current military M662 illuminant which is based upon potassium perchlorate oxidizer formulation.

A monopropellant includes 30-70% by weight of an oxidizer including hydroxylammonium nitrate, 5-50% by weight of a fuel, and a burn rate modifier in a non-zero amount of up to 3% by weight. The burn rate modifier can be selected from vanadium salts, iron salts, and combinations thereof. The monopropellant is a stable liquid between 20 C and 100 C at ambient pressure.

The present invention relates to a method for producing ANFO on the basis of filtration and purification of the residual oils of a mine in a filter truck especially designed and developed for this purpose, with the aim of completely replacing the diesel fuel 2 with said residual oils that have been previously treated in order to mix same with ammonium nitrate, as well as the product resulting from said method. The aim of this invention is to use the residual oil produced in mines in large quantities, as the only combustible agent in the production of ANFO, generating cost savings by completely substituting diesel 2 and additionally eliminating the existing risk inherent in the removal of the residual oil from the mine and the negative impact that it can generate in the environment if it is not used appropriately.

The present invention is directed to an explosive composition comprised of heavy ANFO and expanded polymeric beads that have a density that is less than the density of the heavy ANFO. The expanded polymeric beads have a size that is determined or based on the size of ammonium nitrate prills used in the heavy ANFO portion of the composition. In one embodiment, the expanded polymeric beads that are utilized in the composition are at least 70% of the lower limit of the mesh size of the predominant ammonium nitrate prill mesh size. In another embodiment, the expanded polymeric beads are at least 70% of a size that is related to the average mesh size of the ammonium nitrate prills.
