A sealant applied to at least a portion of the particles, wherein the sealant substantially prevents the gas from escaping the porosities. The matrix is a flame-retardant composition adapted to be applied to various surfaces. The matrix may also function as the sealant. The sealant is formed of a material that will break down and release the gas in the presence of water or flame or other selected conditions. The sealant may be a polymer material. This solves the problem of applying flame-retardant qualities to various surfaces. ## Claims ### Claim 1 A flame-retardant composition comprising: a plurality of particles, each particle having at least one porosity therein; a nonflammable gas occupying the porosity at a pressure elevated above ambient conditions; and a gas-impermeable sealant on each of the particles, the sealant maintaining the gas at elevated pressure in the porosity_and substantially preventing escape of the gas from the porosity, the sealant breaking down to release the gas from the porosities under selected conditions, wherein the sealant is a matrix material in which the particles are dispersed. ### Claim 2 (depends on 1) The composition according to claim 1, wherein the nonflammable gas is carbon dioxide. ### Claim 3 (depends on 1) The composition according to claim 1, wherein the particles are halloysite. ### Claim 4 (depends on 1) The composition according to claim 1, wherein the particles are cyclodextrin. ### Claim 5 (depends on 1) The composition according to claim 1, wherein the sealant is a material that will break down and release the gas in the presence of heat or flame. ### Claim 6 (depends on 1) The composition according to claim 1, wherein the particles are zeolite. ### Claim 7 (depends on 1) The composition according to claim 1, wherein the at least one porosity in each of the plurality of particles is open to an atmosphere and the sealant obstructs the opening to prevent escape of the gas. ### Claim 8 A flame-retardant composition comprising: a plurality of particles, each particle having at least one porosity; a nonflammable, oxygen-displacing gas occupying the porosity at a pressure elevated above ambient conditions; and a gas-impermeable sealant applied to at least a portion of each of the particles, wherein the sealant substantially prevents the gas from escaping the porosity in each particle until exposure to heat or flame. ### Claim 9 (depends on 8) The composition according to claim 8, wherein the sealant is a matrix material in which the particles are dispersed. ### Claim 10 (depends on 8) The composition according to claim 8, wherein the nonflammable gas is carbon dioxide. ### Claim 11 (depends on 8) The composition according to claim 8, wherein the particles are halloysite. ### Claim 12 (depends on 8) The composition according to claim 8, wherein the particles are cyclodextrin. ### Claim 13 (depends on 8) The composition according to claim 8, wherein the sealant is a material that will break down and release the gas in the presence of heat or flame. ### Claim 14 (depends on 8) The composition according to claim 8, wherein the at least one porosity in each of the plurality of particles is open to an atmosphere and the sealant obstructs the opening to prevent escape of the gas. ### Claim 14 A flame-retardant composition comprising: a plurality of particles, each particle having at least one porosity, each porosity having at least one open end; a nonflammable, oxygen-displacing gas occupying the porosity at a pressure elevated above ambient conditions; and a gas-impermeable sealant applied to at least a portion of each of the particles, wherein the sealant obstructs the open end of the porosity and substantially prevents the gas from escaping the porosity in each particle until exposure to heat or flame. ### Claim 15 (depends on 14) The composition according to claim 14, wherein the sealant is a matrix material in which the particles are dispersed. ### Claim 16 (depends on 14) The composition according to claim 14, wherein the nonflammable gas is carbon dioxide. ### Claim 17 (depends on 14) The composition according to claim 14, wherein the particles are halloysite. ### Claim 18 (depends on 14) The composition according to claim 14, wherein the particles are cyclodextrin. ### Claim 19 (depends on 14) The composition according to claim 14, wherein the sealant is a material that will break down and release the gas in the presence of heat or flame.
