Abstract |
Ceramic chemists have often found that the nature of
the cations saturating the kaolin determines, sometimes to a
large extent, its ceramic behaviour (Norton1). A quantitative
treatment of this problem is beset with several difficulties,
For example, it is known that the control of exchangeable
bases is important for clays used in casting slips, but it has
not been investigated whether the degree of saturation with
Na+ is more important than anything else. If so, what is the
optimum saturation? Again, what is true of Na+ holds,
possibly to a greater or less extent, for other ions. It is
very likely that if a quantitative treatment of these
questions is at all possible, it should be sought in the cationic
activities of the respective clays. |
