Sulfur-free propellant compositions
First Claim
1. A propellant composition comprising a sulfur free deflagrating gas generating formulation including oxidizing and reducing agents selected from the group consisting of carbon, sugars, nitrate salts, perchlorate salts, benzoate salts, and mixtures thereof, a first ignition aid of sodium nitrobenzoate salt, and a flow agent comprising tricalcium phoshate.

Abstract
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.
