ALUMINIUM SILICATE
Aluminium silicate (or aluminum silicate) is a name commonly applied to chemical compounds which are derived from aluminium oxide, Al2O3 and silicon dioxide, SiO2 which may be anhydrous or hydrated, naturally occurring as minerals or synthetic. Their chemical formulae are often expressed as xAl2O3·ySiO2·zH2O. It is known as E number E559.

The polyaluminum zirconium silicate sulfate (PAZS) coagulants were then obtained by curing for an additional 12 hrs. Polyaluminum silicate sulfate (PASS) can be obtained without adding Zr salt. After curing, the product was dried at 60 °C for 12 hrs in a vacuum dryer, which led to the formation of solid state PAZS.
