Abstract

A reduced toxicity baseline screening smoke composition and method includes a mixture of lithium perchlorate and boron. The mixture may further include a burn rate modifier and any of an inorganic chloride coolant and a carbonate coolant. The lithium perchlorate may be in the range of 75% to 95% parts by weight. The boron may be in the range of 5% to 25% parts by weight. The any of an inorganic chloride coolant and a carbonate coolant may be in the range of 5% to 25% parts by weight. The mixture may include boron oxide.

First claim

What is claimed is:

1. A reduced toxicity baseline screening smoke composition comprising a mixture of lithium perchlorate, boron, a burn rate modifier and any of an inorganic chloride coolant and a carbonate coolant.

2. The composition of claim 1 , wherein said lithium perchlorate is in the range of 75% to 95% parts by weight.

3. The composition of claim 1 , wherein said boron is in the range of 5% to 25% parts by weight.

4. The composition of claim 1 , wherein said any of an inorganic chloride coolant and a carbonate coolant is in the range of 5% to 25% parts by weight.

5. The composition of claim 1 , wherein said mixture includes boron oxide.

6. A method of consolidating a reduced toxicity baseline screening smoke composition, said method comprising creating a mixture of lithium perchlorate, boron, a burn rate modifier and any of an inorganic chloride coolant and a carbonate coolant.

7. The method of claim 6 , wherein said lithium perchlorate is in the range of 75% to 95% parts by weight.

8. The method of claim 6 , wherein said boron is in the range of 5% to 25% parts by weight.

9. The method of claim 6 , wherein said any of an inorganic chloride coolant and a carbonate coolant is in the range of 5% to 25% parts by weight.

10. The method of claim 6 , further comprising mixing boron oxide in said mixture.

11. The method of claim 6 , further comprising inserting said mixture at loading pressures between 2,500 and 5,000 pounds per square inch into a canister.

12. The method of claim 6 , further comprising inserting said mixture at loading pressures between 5,000 and 7,500 pounds per square inch into a canister.

13. The method of claim 6 , further comprising inserting said composition into any of a canister of a grenade, a smoke pot, a mortar round, a shoulder fired missile, and an artillery round.

14. A method of consolidating a reduced toxicity baseline screening smoke composition, said method comprising creating a mixture comprising lithium perchlorate in the range of 75% to 95% parts by weight, boron in the range of 5% to 25% parts by weight, and a burn rate modifier and any of an inorganic chloride coolant and a carbonate coolant in the range of 5% to 25% parts by weight in said mixture.

15. The method of claim 14 , further comprising mixing boron oxide in said mixture.

16. The method of claim 14 , further comprising inserting said mixture at loading pressures between 2,500 and 5,000 pounds per square inch into a canister.

17. The method of claim 14 , further comprising inserting said mixture at loading pressures between 5,000 and 7,500 pounds per square inch into a canister.
