Abstract
Attrition-resistant binders can be prepared by a process wherein a slurry of delaminated and calcined clay particles is brought to either a low pH level (e.g., 1.0 to 3.0) or to a high pH level (e.g., 14.0 to 10.0) and mixed with a phosphate-containing compound in a concentration of from about 2.0 to about 20.0 weight percent. Preferably, the resulting slurry is spray dried and the particulate products of the spray drying are then calcined to produce attrition-resistant binder particles.
