1. A method for making propellant for use in an inflator located in a vehicle, comprising:

  • providing phase-stabilized ammonium nitrate by integrating potassium nitrate with ammonium nitrate such that said ammonium nitrate and said potassium nitrate are fused together;

    mixing said phase-stabilized ammonium nitrate with at least fibrous cellulose to form a mixture, wherein said fibrous cellulose is between 6% and 12% by weight of said mixture of said phase-stabilized ammonium nitrate and said at least fibrous cellulose;

    forming a thin, continuous length of propellant having a first density from said mixture of said phase-stabilized ammonium nitrate and said at least fibrous cellulose; and

    working said thin, continuous length of propellant to provide said thin, continuous length of propellant with a second density greater than said first density.
