摘要

A process for producing pigmentary titanium dioxide that has improved process bulk density and carbon black undertones, consisting of reacting titanium tetrachloride and a vapor-containing oxygen-containing gas at a temperature in the reaction zone of at least 800ºC, in the presence of approximately 50 to 100,000 parts per million, with respect to the produced TiO2, of water vapor, and from approximately 0.01 to 10,000 parts per million, with respect to the TiO2, of a metal ion nucleant selected from the group consisting of sodium, potassium, lithium, rubidium, cesium, calcium, barium, strontium and cerium, and then recover the resulting titanium dioxide pigment.
