Definitions

  • the first step in the process of the present inven ⁇ tion comprises the formation of an aqueous slurry of the titanium dioxide pigment to be treated, adjustment of the slurry to an alkaline pH and the heating of the pH adjusted slurry to the requisite elevated temperatures.
  • the aqueous slurry is formed by suspend ⁇ ing the wet milled and hydroclassified pigment in an aqueous medium such as water in an amount sufficient to provide a slurry containing from about 20 to about 45 weight percent solids.
  • a dispersing agent, soluble in the aqueous medium employed also may be added to the slurry to maintain the pigment in a highly dispersed state in the aqueous medium.
  • suitable dispersing agents include such water soluble inorganic compounds as sodium hexa- metaphosphate, sodium polyphosphate, sodium hydroxide, and the like.
