ABSTRACT:
An inorganic substance composition comprising at least 50% by weight of a finely divided inorganic substance and 2 to 50% by weight of a fiber forming organic polymeric material and having a specific surface area of more than 2 m.sup.2 /g is described. The composition is prepared by preparing a liquid suspension from the inorganic substance, the organic polymeric material and a solvent; heating the liquid suspension to at least 100.degree. C to dissolve the organic polymeric material in the solvent; and then extruding the heated liquid suspension at a pressure equal to or higher than the vapor pressure of the solvent through an orifice into a zone of a lower pressure to evaporate the solvent.
