1. A method for preparing anhydrous gas generants comprising the steps of:

  • (a) preparing a mixture of oxidizer particles having a number average particle size of about 1 micron to about 20 microns and fuel particles having a number average particle size of about 1 micron to about 100 microns wherein the fuel is at least one fuel species selected from the group consisting of tetrazoles in a medium selected from the group consisting of alcohol, ketone, water, and mixtures thereof;

    (b) agglomerating the mixture to obtain particles having a weight average particle size of about 100 mesh to about 14 mesh;

    (c) drying the agglomerate to obtain anhydrous particles; and

    (d) shaping the anhydrous particles into a desired shape.
