Abstract

Official abstract text for this publication.

Generally, the instant disclosure relates to fertilizer compositions and methods of making and using the same. More specifically, the instant disclosure relates to blast suppressant and/or blast resistant ammonium nitrate fertilizer compositions, as well as methods of making and using the same.

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 clay, 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 13.5 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.
