Dear Friends,
A lot is said about additives for deflocculation.
Science books tell us that this phenomenon is due to the affects the =
alkalies have, neutralising electrostatic charges on clay particles. We =
are also told that Cations with large radii disrupt the water structures =
of plastic clay.
But has anything been written about the effects of the anions which are =
added. These include Carbonate, Phosphate and Silicate substances and =
all of them seem to have ions whose sizes are double those of the =
cations.=20
So, what is known ? and if it is not known, is it important?
Best regards,
