The fluidization of clay slips begins with neutralization of the acidic clay. This involves the following 4 stages:
1. Neutralization of H+ (substitution of H+ by Na+) H+ Ca2+ clay + Na2CO3 -> Na+ Ca2+ clay + NaHCO3
2. Cation exchange (substitution of Ca2+ in the double layer by Na+)
3. Anion Adsorption on the positively charged […]
