Abstract

A combustible aerosol composition is disclosed including an oxidizer including potassium bromate, a fuel including potassium cyanurate, and a hydrated mineral composition including potassium hydromagnesite.

First claim

The invention claimed is:

1. A combustible aerosol composition, comprising
an oxidizer comprising potassium bromate;
a fuel comprising potassium cyanurate; and
a hydrated mineral comprising 90-99 wt. % hydromagnesite and 1-10 wt. % of one or more other hydrated minerals having a dehydration decomposition temperature in the range of 200° C. to 600° C.

2. The composition of claim 1 , wherein the one or more other hydrated minerals are according to the formula (M 2 ) k (M 3 ) m (X 2 ) n (X 3 ) o Y p , where M 2 is selected from a Group IA atom, Group IIA atom, Group IIIA atom, M 3 is selected from a Group IIA atom, Group IIIA, and a transition metal atom, X 2 is a hydroxyl anion, X 3 is a carbonate anion, Y represents ·(H 2 O), k, m, n, o, and p are each zero or each independently positive numbers, with the proviso that k and m cannot both be zero and that n and p cannot both be zero, and the values of k, m, n, o and p are such that they balance the charges of M 2 , M 3 , X 2 , and X 3 .

3. The composition of claim 1 , wherein the one or more other hydrated minerals are selected from hydrotalcite, dypingite, brucite, gibbsite or mixtures thereof.

4. The composition of claim 1 , wherein the hydrated mineral consists of hydromagnesite.

5. The composition of claim 1 , further comprising potassium bromide.

6. The composition of claim 1 , further comprising carbon black.

7. The composition of claim 1 , comprising 55-75 wt. % potassium bromate, 12-36 wt. % potassium cyanurate, 1-10 wt. % hydromagnesite, and 0-10 wt. % one or more additional components selected from oxidizers, fuels, hydrated minerals, opacifiers, flame retardants, or other additives.

8. A combustible aerosol composition, comprising
an oxidizer comprising potassium bromate derived from potassium bromate particles having a particle size of 1-100 μm;
a fuel comprising potassium cyanurate derived from potassium cyanurate particles having a particle size of 1-100 μm; and
a hydrated mineral comprising hydromagnesite derived from hydromagnesite particles having a particle size of less than 100 μm.

9. The composition of claim 8 , wherein the potassium bromate is derived from potassium bromate particles having a particle size of 1-50 μm, the potassium cyanurate is derived from potassium cyanurate particles having a particle size of 1-50 μm, and the hydromagnesite is derived from hydromagnesite particles having a particle size of less than 40 μm.

10. The composition of claim 8 , wherein the potassium bromate is derived from potassium bromate particles having a particle size of 1-30 μm, the potassium cyanurate is derived from potassium cyanurate particles having a particle size of 1-30 μm, and the hydromagnesite is derived from hydromagnesite particles having a particle size of less than 10 μm.

11. A combustible aerosol composition, comprising
40-87 wt. % potassium bromate derived from potassium bromate particles having a particle size of 1-100 μm;
10-50 wt. % potassium cyanurate derived from potassium cyanurate particles having a particle size of 1-100 μm;
greater than 0 wt. % to 10 wt. % a hydrated mineral comprising hydromagnesite derived from hydromagnesite particles having a particle size of less than 100 μm; and
0-50 wt. % one or more additional components selected from oxidizers, fuels, hydrated minerals, opacifiers, flame retardants, or other additives.

12. The composition of claim 11 , wherein the hydrated mineral comprises 90-99 wt. % hydromagnesite and 1-10 wt. % of one or more other hydrated minerals having a dehydration decomposition temperature in the range of 200° C. to 600° C.

13. The composition of claim 12 , wherein the one or more other hydrated minerals are selected from hydrotalcite, dypingite, brucite, gibbsite, or mixtures thereof.

14. The composition of claim 11 , comprising from greater than 0 wt. % to 20 wt. % potassium bromide.

15. The composition of claim 14 , comprising from greater than 0 wt. % to 5 wt. % carbon black.

16. The composition of claim 11 , comprising from greater than 0 wt. % to 5 wt. % carbon black.

17. A method of producing an aerosol, comprising combusting the composition of claim 1 .

18. An aerosol dispensing device, comprising a housing, a combustion chamber, the composition of claim 1 disposed in the combustion chamber, an igniter, and an opening from the combustion chamber for dispensing aerosol produced by combustion of the composition of claim 1 .

19. An aerosol dispensing device, comprising a housing, a combustion chamber, the composition of claim 11 disposed in the combustion chamber, an igniter, and an opening from the combustion chamber for dispensing aerosol produced by combustion of the composition of claim 11 .
