网页Palygorskite, a fibrous magnesium aluminum silicate. The structure of palygorskite contains extended silicon-oxygen sheets, justifying the retention of the mineral in the layer silicate family, but the tetrahedral SiO4 groups forming these sheets are oriented in such a manner as to develop extended.

网页Palygorskite (formerly called attapulgite) is a lath-like or fibrous clay mineral with a structure consisting of short and alternating inverted 2:1 sheets or ribbons. These ribbons have an average width (along the Y direction) of two linked tetrahedral chains in palygorskite (and three linked chains in sepiolite).

网页2022年1月1日 · Palygorskite is the aluminic term of the sepiolite-palygorskite polysomatic series (Suárez and García-Romero, 2011, Suárez and García-Romero, 2013), in which tunnels are located inside of the crystals and channels on the surface, all running parallel to the fibre, which result in a high surface area. In recent decades, the uses of and ...
