The variation with pH of the electrophoretic mobility of suspended particles has been determined for Fe2O3, TiO2, SnO2, SiO2, Al2O3, and for a number of synthetic aluminosilicates. The properties of the natural substances have been compared with those of synthetic materials before and after ignition at high temperatures. In general, the dehydration and recrystallization caused by ignition of the precipitated materials tend to produce surfaces resembling those of the natural crystals.
