Abstract: Fire-resistant containers made with inorganic polymer material. One type of container comprises a hollow body in the form of a matrix of inorganic polymer material. Other types of containers comprise a shell of non-inorganic polymer having interior or exterior surfaces treated with inorganic polymer material. Optionally, the hollow body further comprises filler material bound in the inorganic polymer material. For example, the filler material may comprise wound filaments. Some types of containers, e.g., munitions containers and firesafes, comprise a hollow body having an opening covered by a door, lid, or other closure device, the hollow body and closure device comprising inorganic polymer material.
