First claim
Opening claim text (preview).
What is claimed is: 1 . A fertilizer composition, comprising: an ammonium nitrate material; and an effective amount of a stabilizer material to result in. a specific impulse of not greater than 13.5 kPa*ms/kg when measured in accordance with a blast propagation test; wherein the stabilizer material comprises an aluminum production byproduct, wherein the stabilizer material is at least 12.5 wt. % of the total fertilizer composition. 2 . The composition of claim 1 , wherein the aluminum production byproduct comprises: a layered double hydroxide. 3 . The composition of claim 1 , wherein the stabilizer material comprises hydrocalumite. 4 . The composition of claim 1 , wherein the stabilizer material comprises hydrotalcite. 5 . The composition of claim 1 , wherein the stabilizer material comprises hydroxyapatite. 6 . In some embodiments, the stabilizer material comprises an additive. 7 . A fertilizer composition, comprising: an ammonium nitrate material; and an effective amount of a stabilizer material to result in a specific impulse of not greater than 13.5 kPa*ms/kg when measured in accordance with a blast propagation test; wherein the stabilizer material is selected from the group consisting of: layered double hydroxide, apatite, and combinations thereof; wherein the stabilizer material is at least 12.5 wt. % of the total fertilizer composition. 8 . The fertilizer of claim 7 , further comprising a filler material. 9 . The fertilizer of claim 8 , wherein the filler material is selected from the group consisting of: bauxite residue, fire day, red lime, and combinations thereof. 10 . A fertilizer composition, comprising: an ammonium nitrate material; and an effective amount of a stabilizer material to result in a specific impulse of not greater than 13.5 kPa*ms/kg when measured in accordance with a blast propagation test; wherein the stabilizer material comprises hydrotalcite, wherein the stabilizer material is at least 12.5 wt. % to not greater than 20 wt. % of the total fertilizer composition. 11 . A fertilizer composition, comprising: an ammonium nitrate material; and an effective amount of a stabilizer material to result in a specific impulse of not greater than 13.5 kPa*ms/kg when measured in accordance with a blast propagation test; wherein the stabilizer material comprises hydrotalcite, wherein the stabilizer material is at least 12.5 wt. % to not greater than 20 wt. % of the total fertilizer composition. 12 . A fertilizer composition, comprising: an ammonium nitrate material; and an effective amount of a stabilizer material to result in a specific impulse of not greater than 115 kPa*ms/kg when measured in accordance with a blast propagation test; wherein the stabilizer material comprises hydrocalumite, wherein the stabilizer material is at least 12.5 wt. % to not greater than 20 wt. % of the total fertilizer composition. 13 . A fertilizer composition, comprising: an ammonium nitrate material; and an effective amount of a stabilizer material to result in a specific impulse of not greater than 13.5 kPa*ms/kg when measured in accordance with a blast propagation test; wherein the stabilizer material comprises apatite, wherein the stabilizer material is at least 12.5 wt. % to not greater than 20 wt. % of the total fertilizer composition.
