Sulfur free propellant compositions for use as a blackpowder substitute in firearms, munitions, and pyrotechnics to form combustion byproducts that are water soluble and are free of corrosive sulfur compounds. Formulations include an ignition aid of a gluconic acid salt or an alkali metal nitrobenzoate salt or a mixture of the two salts in combination with various known oxidizing and reducing agents and with various known propellant additives. The oxidizing and reducing agents may be selected from the group consisting of carbon, lactose, potassium nitrate, potassium perchlorate, sodium benzoate, and mixtures thereof. The propellant additives may be selected from the group consisting of binders, burning rate modifiers, flow agents, colorants, coating agents, moisture retardants and mixtures thereof.
A sulfur replacement composition for deflagrating gas generating formulations, said sulfur replacement composition comprising a gluconic acid salt.
A sulfur replacement composition for deflagrating gas generating formulations, said sulfur replacement composition comprising a sodium nitrobenzoate salt.
A propellant composition comprising a sulfur free deflagrating gas generating formulation, and a first ignition aid of a gluconic acid salt.
A propellant composition comprising a sulfur free deflagrating gas generating formulation, and a first ignition aid of sodium nitrobenzoate salt.
A combustible charge which forms no corrosive sulfur-containing byproducts of combustion, said charge comprising:
