The interaction of two commercially available phosphate ester dispersants with calcined alumina has been investigated using the techniques of flow calorimetry and electrophoresis. Flow calorimetric experiments have shown that these dispersants chemically interact with the surface of calcined alumina. The electrical charging of alumina particles in an iso-octane solution containing a phosphate ester indicates that an acid-base interaction mechanism is operative in this system.
