Disclosed are compositions of flocced mineral materials combined with fibers and/or binders. These compositions may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.5 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of an exchange cation that is derived from guanidine or compounds closely related thereto.

A flocced mineral material which comprises (1) a binder and (2) a swelled layer silicate gel that has an average charge per structural unit that ranges from about -0.5 to about -1, said silicate containing at least some interstitial cations that have the formula [R1C(R2)R3]+wherein R1, R2, and R3 ar

A flocced mineral material which comprises (1) a binder and (2) a swelled layer silicate gel that has an average charge per structural unit that ranges from about -0.5 to about -1, said silicate containing at least some interstitial cations that have the formula [R1C(R2)R3]+wherein R1, R2, and R3 are independently selected from NH2 and CH3; provided, however, that at least two or more of R1, R2, and R3 are NH2 but further providing that one or more of the hydrogen atoms of R1, R2, and R3 may instead be a substitutent selected from: a C1 to C5 alkyl, a C2 to C5 alkenyl and a C2 to C5 alkynyl wherein these substituents may be linked to form one or more rings which may be saturated, unsaturated or aromatic; and further, provided that the silicate is a water swelling body of (a) vermiculite, (b) mica, or (c) a mixture of vermiculite and mica.
