Abstract
Abstract Disclosed are fire-resistant paper-like materials. These materials are prepared by embedding a fabric in a layered inorganic silicate matrix that has an average charge per structural unit that ranges from about -0.4 to -1 and which contains at least some interstitial cations that are selected from the group consisting of guanidine and multiamine derived cations.
