  • Effect of chemical composition on the surface charge

    1. Introduction. Pyrophyllite is a hydrous layered aluminum silicate Al 2 Si 4 O 10 (OH) 2 with a kind of 2 1 structure consists of individual sheets of Al(O OH) 6 octahedra sandwiched between sheets of SiO 4 tetrahedra. The pyrophyllite is theoretically composed of 67 SiO 2 28 Al 2 O 3 and 5 H 2 O in which Al is likely to be replaced by Fe or some like Mg Ca Na or K .
