Abstract

An obscurant-emitting composition may comprise an oxidizer comprising a cation comprising at least one of an alkali metal or an alkaline earth metal, and an anion comprising at least one of nitrate, chlorate, bromate, iodate, perchlorate, periodate, or chlorite; a fuel; and a hydrated salt composition, wherein the obscurant-emitting composition comprises between 0.001% and 8% by weight hydrated salt composition.

First claim

What is claimed is:

1. An obscurant-emitting system, comprising:
a vessel;
an obscurant-emitting composition comprised within the vessel comprising an oxidizer, a fuel, and a hydrated salt composition,
wherein, the obscurant-emitting composition comprises between 3% and 4% by weight the hydrated salt composition,
wherein the hydrated salt composition comprises a primary compound comprising hydromagnesite and a secondary compound, and wherein the hydrated salt composition comprises between 90% and 99.9% by weight hydromagnesite and between 0.1% and 10% by weight the secondary compound.

2. The obscurant-emitting system of claim 1 , further comprising an ignition device configured to ignite the obscurant-emitting composition.

3. The obscurant-emitting system of claim 1 , wherein the primary compound further comprises at least one of artinite, hydrotalcite, dypingite, giorgiosite, brucite, gibbsite, or protomagnesite.

4. The obscurant-emitting system of claim 1 , wherein the secondary compound comprises at least one of hydromagnesite, artinite, hydrotalcite, dypingite, giorgiosite, brucite, gibbsite, or protomagnesite.

5. The obscurant-emitting system of claim 4 , wherein the oxidizer comprises at least one of sodium bromate or potassium bromate.

6. The obscurant-emitting system of claim 5 , wherein the fuel comprises at least one of a salt of cyanuric acid, potassium hydroxyacetate, or magnesium hydroxyacetate.

7. The obscurant-emitting system of claim 6 , wherein the obscurant-emitting composition comprises between 45% and 90% by weight the oxidizer.

8. The obscurant-emitting system of claim 7 , wherein the obscurant-emitting composition comprises between 6% and 40% by weight the fuel.
