Abstract: A process for flame-retarding base materials, such as fibers or foams with a metal oxide, such as silica, nanoparticle-containing composition and materials including a metal oxide, for example silica nano/micro particle-containing coating, layer, or networks. The process utilized allows properties of the coated material to be maintained. Flame-retarded materials are also disclosed. Heterogeneous dispersions of metal oxide, e.g. silica, particles on fibers or foams on a nanometer scale are described and/or the formation of networks/coatings in porous materials. In a particular embodiment, polymeric foams such as polyisocyanurate, polyurea and polyurethane foams include a metal oxide particle-containing coating layer or network that aids in char formation in the event the material is exposed to a flame.
