Combustible fire suppressant aerosol composition
First Claim
1. A combustible fire-suppressant aerosol composition, comprising:
- an oxidizer represented by the formula M1(X1Oy)z, wherein M1 is selected from a Group IA atom, a Group IIA atom, and a Group IIIA atom, X is selected from the group consisting of Cl, Br and I, y is 1-4, and z is 1-3;
a fuel; and
a hydrated salt having a dehydration decomposition temperature greater than 200°
C., represented by the formula (M2)k(M3)m(X2)n(X3)o.(H2O)p where M2 is selected from a Group IA atom, Group IIA atom, Group IIIA atom, M3 is selected from a Group IIA atom, Group IIIA, and a transition atom, X2 is a hydroxyl anion, X3 is a carbonate or sulfate anion, k, m, n, and o are each independently integers that balance the charges of M2, M3, X2, and X3 and p is a number greater than or equal to 1.
